2. BACKGROUND OF THE INVENTION

Obesity, hyperlipidemia, and diabetes have been shown to play a causal role in atherosclerotic cardiovascular diseases, which currently account for a considerable proportion of morbidity in Western society. Further, one human disease, termed "Syndrome X" or "Metabolic Syndrome", is manifested by defective glucose metabolism (insulin resistance), elevated blood pressure (hypertension), and a blood lipid imbalance (dyslipidemia). See e.g. Reaven, 1993, Annu. Rev. Med. 44:121-131.

The evidence linking elevated serum cholesterol to coronary heart disease is overwhelming. Circulating cholesterol is carried by plasma lipoproteins, which are particles of complex lipid and protein composition that transport lipids in the blood. Low density lipoprotein (LDL) and high density lipoprotein (HDL) are the major cholesterol-carrier proteins. LDL is believed to be responsible for the delivery of cholesterol from the liver, where it is synthesized or obtained from dietary sources, to extrahepatic tissues in the body. The term "reverse cholesterol transport" describes the transport of cholesterol from extrahepatic tissues to the liver, where it is catabolized and eliminated. It is believed that plasma HDL particles play a major role in the reverse transport process, acting as scavengers of tissue cholesterol. HDL is also responsible for the removal of non-cholesterol lipid, oxidized cholesterol and other oxidized products from the bloodstream.

Atherosclerosis, for example, is a slowly progressive disease characterized by the accumulation of cholesterol within the arterial wall. Compelling evidence supports the belief that lipids deposited in atherosclerotic lesions are derived primarily from plasma apolipoprotein B (apo B)-containing lipoproteins, which include chylomicrons, CLDL, intermediate-density lipoproteins (IDL), and LDL. The apo B-containing lipoprotein, and in particular LDL, has popularly become known as the "bad" cholesterol. In contrast, HDL serum levels correlate inversely with coronary heart disease. Indeed, high serum levels of HDL are regarded as a negative risk factor. It is hypothesized that high levels of plasma HDL are not only protective against coronary artery disease, but may actually induce regression of atherosclerotic plaque (e.g., see Badimon et al., 1992, Circulation 86:(Suppl. 11)86-94; Dansky and Fisher, 1999, Circulation 100:1762 3.). Thus, HDL has popularly become known as the "good" cholesterol.

2.1. Cholesterol Transport

The fat-transport system can be divided into two pathways: an exogenous one for cholesterol and triglycerides absorbed from the intestine and an endogenous one for cholesterol and triglycerides entering the bloodstream from the liver and other non-hepatic tissue.

In the exogenous pathway, dietary fats are packaged into lipoprotein particles called chylomicrons, which enter the bloodstream and deliver their triglycerides to adipose tissue for storage and to muscle for oxidation to supply energy. The remnant of the chylomicron, which contains cholesteryl esters, is removed from the circulation by a specific receptor found only on liver cells. This cholesterol then becomes available again for cellular metabolism or for recycling to extrahepatic tissues as plasma lipoproteins.

In the endogenous pathway, the liver secretes a large, very-low-density lipoprotein particle (VLDL) into the bloodstream. The core of VLDL consists mostly of triglycerides synthesized in the liver, with a smaller amount of cholesteryl esters either synthesized in the liver or recycled from chylomicrons. Two predominant proteins are displayed on the surface of VLDL, apolipoprotein B-100 (apo B-100) and apolipoprotein E (apo E), although other apolipoproteins are present, such as apolipoprotein CIII (apo CIII) and apolipoprotein CII (apo CII). When VLDL reaches the capillaries of adipose tissue or of muscle, its triglyceride is extracted. This results in the formation of a new kind of particle called intermediate-density lipoprotein (IDL) or VLDL remnant, decreased in size and enriched in cholesteryl esters relative to a VLDL, but retaining its two apoproteins.

In human beings, about half of the IDL particles are removed from the circulation quickly, generally within two to six hours of their formation. This is because IDL particles bind tightly to liver cells, which extract IDL cholesterol to make new VLDL and bile acids. The IDL not taken up by the liver is catabolized by the hepatic lipase, an enzyme bound to the proteoglycan on liver cells. Apo E dissociates from IDL as it is transformed to LDL. Apo B-100 is the sole protein of LDL.

Primarily, the liver takes up and degrades circulating cholesterol to bile acids, which are the end products of cholesterol metabolism. The uptake of cholesterol-containing particles is mediated by LDL receptors, which are present in high concentrations on hepatocytes. The LDL receptor binds both apo E and apo B-100 and is responsible for binding and removing both IDL and LDL from the circulation. In addition, remnant receptors are responsible for clearing chylomicrons and VLDL remnants (i.e., IDL). However, the affinity of apo E for the LDL receptor is greater than that of apo B-100. As a result, the LDL particles have a much longer circulating life span than IDL particles; LDL circulates for an average of two and a half days before binding to the LDL receptors in the liver and other tissues. High serum levels of LDL, the "bad" cholesterol, are positively associated with coronary heart disease. For example, in atherosclerosis, cholesterol derived from circulating LDL accumulates in the walls of arteries. This accumulation forms bulky plaques that inhibit the flow of blood until a clot eventually forms, obstructing an artery and causing a heart attack or stroke.

Ultimately, the amount of intracellular cholesterol liberated from the LDL controls cellular cholesterol metabolism. The accumulation of cellular cholesterol derived from VLDL and LDL controls three processes. First, it reduces the ability of the cell to make its own cholesterol by turning off the synthesis of HMGCoA reductase, a key enzyme in the cholesterol biosynthetic pathway. Second, the incoming LDL-derived cholesterol promotes storage of cholesterol by the action of cholesterol acyltransferase ("ACAT"), the cellular enzyme that converts cholesterol into cholesteryl esters that are deposited in storage droplets. Third, the accumulation of cholesterol within the cell drives a feedback mechanism that inhibits cellular synthesis of new LDL receptors. Cells, therefore, adjust their complement of LDL receptors so that enough cholesterol is brought in to meet their metabolic needs, without overloading (for a review, see Brown & Goldstein, in The Pharmacological Basis Of Therapeutics, 8th Ed., Goodman & Gilman, Pergamon Press, New York, 1990, Ch. 36, pp. 874-896).

High levels of apo B-containing lipoproteins can be trapped in the subendothelial space of an artery and undergo oxidation. The oxidized lipoprotein is recognized by scavenger receptors on macrophages. Binding of oxidized lipoprotein to the scavenger receptors can enrich the macrophages with cholesterol and cholesteryl esters independently of the LDL receptor. Macrophages can also produce cholesteryl esters by the action of ACAT. LDL can also be complexed to a high molecular weight glycoprotein called apolipoprotein(a), also known as apo(a), through a disulfide bridge. The LDL-apo(a) complex is known as Lipoprotein(a) or Lp(a). Elevated levels of Lp(a) are detrimental, having been associated with atherosclerosis, coronary heart disease, myocardial infarction, stroke, cerebral infarction, and restenosis following angioplasty.

2.2. Reverse Cholesterol Transport

Peripheral (non-hepatic) cells predominantly obtain their cholesterol from a combination of local synthesis and uptake of preformed sterol from VLDL and LDL. Cells expressing scavenger receptors, such as macrophages and smooth muscle cells, can also obtain cholesterol from oxidized apo B-containing lipoproteins. In contrast, reverse cholesterol transport (RCT) is the pathway by which peripheral cell cholesterol can be returned to the liver for recycling to extrahepatic tissues, hepatic storage, or excretion into the intestine in bile. The RCT pathway represents the only means of eliminating cholesterol from most extrahepatic tissues and is crucial to the maintenance of the structure and function of most cells in the body.

The enzyme in blood involved in the RCT pathway, lecithin:cholesterol acyltransferase (LCAT), converts cell-derived cholesterol to cholesteryl esters, which are sequestered in HDL destined for removal. LCAT is produced mainly in the liver and circulates in plasma associated with the HDL fraction. Cholesterol ester transfer protein (CETP) and another lipid transfer protein, phospholipid transfer protein (PLTP), contribute to further remodeling the circulating HDL population (see for example Bruce et al., 1998, Annu. Rev. Nutr. 18:297 330). PLTP supplies lecithin to HDL, and CETP can move cholesteryl esters made by LCAT to other lipoproteins, particularly apoB-containing lipoproteins, such as VLDL. HDL triglycerides can be catabolized by the extracellular hepatic triglyceride lipase, and lipoprotein cholesterol is removed by the liver via several mechanisms.

Each HDL particle contains at least one molecule, and usually two to four molecules, of apolipoprotein A I (apo A I). Apo A I is synthesized by the liver and small intestine as preproapolipoprotein, which is secreted as a proprotein that is rapidly cleaved to generate a mature polypeptide having 243 amino acid residues. Apo A I consists mainly of a 22 amino acid repeating segment, spaced with helix-breaking proline residues. Apo A I forms three types of stable structures with lipids: small, lipid-poor complexes referred to as pre-beta-1 HDL; flattened discoidal particles, referred to as pre-beta-2 HDL, which contain only polar lipids (e.g., phospholipid and cholesterol); and spherical particles containing both polar and nonpolar lipids, referred to as spherical or mature HDL (HDL3 and HDL2). Most HDL in the circulating population contains both apo A I and apo A II, a second major HDL protein. This apo A I- and apo A II-containing fraction is referred to herein as the AT/AII-HDL fraction of HDL. But the fraction of HDL containing only apo A I, referred to herein as the AI HDL fraction, appears to be more effective in RCT. Certain epidemiologic studies support the hypothesis that the AI-HDL fraction is antiartherogenic (Parra et al., 1992, Arterioscler. Thromb. 12:701-707; Decossin et al., 1997, Eur. J. Clin. Invest. 27:299-307).

Although the mechanism for cholesterol transfer from the cell surface is unknown, it is believed that the lipid-poor complex, pre-beta-1 HDL, is the preferred acceptor for cholesterol transferred from peripheral tissue involved in RCT. Cholesterol newly transferred to pre-beta-1 HDL from the cell surface rapidly appears in the discoidal pre-beta-2 HDL. PLTP may increase the rate of disc formation (Lagrost et al., 1996, J. Biol. Chem. 271:19058-19065), but data indicating a role for PLTP in RCT is lacking. LCAT reacts preferentially with discoidal and spherical HDL, transferring the 2-acyl group of lecithin or phosphatidylethanolamine to the free hydroxyl residue of fatty alcohols, particularly cholesterol, to generate cholesteryl esters (retained in the HDL) and lysolecithin. The LCAT reaction requires an apolipoprotein such as apo A I or apo A-IV as an activator. ApoA-I is one of the natural cofactors for LCAT. The conversion of cholesterol to its HDL-sequestered ester prevents re-entry of cholesterol into the cell, resulting in the ultimate removal of cellular cholesterol. Cholesteryl esters in the mature HDL particles of the AI-HDL fraction are removed by the liver and processed into bile more effectively than those derived from the AI/AII-HDL fraction. This may be due, in part, to the more effective binding of AI-HDL to the hepatocyte membrane. Several HDL receptors have been identified, the most well characterized of which is the scavenger receptor class B, type I (SR BI) (Acton et al., 1996, Science 271:518-520). The SR-BI is expressed most abundantly in steroidogenic tissues (e.g., the adrenals), and in the liver (Landshulz et al., 1996, J. Clin. Invest. 98:984-995; Rigotti et al., 1996, J. Biol. Chem. 271:33545-33549). Other proposed HDL receptors include HB1 and HB2 (Hidaka and Fidge, 1992, Biochem J. 15:161 7; Kurata et al., 1998, J. Atherosclerosis and Thrombosis 4:112 7).

While there is a consensus that CETP is involved in the metabolism of VLDL- and LDL-derived lipids, its role in RCT remains controversial. However, changes in CETP activity or its acceptors, VLDL and LDL, play a role in "remodeling" the HDL population. For example, in the absence of CETP, the HDL becomes enlarged particles that are poorly removed from the circulation (for reviews on RCT and HDL, See Fielding & Fielding, 1995, J. Lipid Res. 36:211-228; Barrans et al., 1996, Biochem. Biophys. Acta. 1300:73-85; Hirano et al., 1997, Arterioscler. Thromb. Vasc. Biol. 17:1053-1059).

2.3. Reverse Transport of Other Lipids

HDL is not only involved in the reverse transport of cholesterol, but also plays a role in the reverse transport of other lipids, i.e., the transport of lipids from cells, organs, and tissues to the liver for catabolism and excretion. Such lipids include sphingomyelin, oxidized lipids, and lysophophatidylcholine. For example, Robins and Fasulo (1997, J. Clin. Invest. 99:380 384) have shown that HDL stimulates the transport of plant sterol by the liver into bile secretions.

2.4. Peroxisome Proliferator Activated Receptor Pathway

Peroxisome proliferators are a structurally diverse group of compounds that, when administered to rodents, elicit dramatic increases in the size and number of hepatic and renal peroxisomes, as well as concomitant increases in the capacity of peroxisomes to metabolize fatty acids via increased expression of the enzymes required for the .beta.-oxidation cycle (Lazarow and Fujiki, 1985, Ann. Rev. Cell Biol. 1:489 530; Vamecq and Draye, 1989, Essays Biochem. 24:1115 225; and Nelali et al., 1988, Cancer Res. 48:5316 5324). Chemicals included in this group are the fibrate class of hypolipidemic drugs, herbicides, and phthalate plasticizers (Reddy and Lalwani, 1983, Crit. Rev. Toxicol. 12:1 58). Peroxisome proliferation can also be elicited by dietary or physiological factors, such as a high fat diet and cold acclimatization.

Insight into the mechanism whereby peroxisome proliferators exert their pleiotropic effects was provided by the identification of a member of the nuclear hormone receptor superfamily activated by these chemicals (Isseman and Green, 1990, Nature 347:645 650). This receptor, termed peroxisome proliferator activated receptor .alpha. (PPAR.alpha.), was subsequently shown to be activated by a variety of medium and long chain fatty acids. PPAR.alpha. activates transcription by binding to DNA sequence elements, termed peroxisome proliferator response elements (PPRE), in the form of a heterodimer with the retinoid X receptor (RXR). RXR is activated by 9-cis retinoic acid (see Kliewer et al., 1992, Nature 358:771 774; Gearing et al., 1993, Proc. Natl. Acad. Sci. USA 90:1440 1444, Keller et al., 1993, Proc. Natl. Acad. Sci. USA 90:2160 2164; Heyman et al., 1992, Cell 68:397 406, and Levin et al., 1992, Nature 355:359 361). Since the discovery of PPAR.alpha., additional isoforms of PPAR have been identified, e.g., PPAR.beta., PPAR.gamma. and PPAR.delta., which have similar functions and are similarly regulated.

PPARs have been identified in the enhancers of a number of gene-encoding proteins that regulate lipid metabolism. These proteins include the three enzymes required for peroxisomal t-oxidation of fatty acids; apolipoprotein A-I; medium chain acyl-CoA dehydrogenase, a key enzyme in mitochondrial .beta.-oxidation; and aP2, a lipid binding protein expressed exclusively in adipocytes (reviewed in Keller and Whali, 1993, TEM, 4:291 296; see also Staels and Auwerx, 1998, Atherosclerosis 137 Suppl:S19 23). The nature of the PPAR target genes coupled with the activation of PPARs by fatty acids and hypolipidemic drugs suggests a physiological role for the PPARs in lipid homeostasis.

Pioglitazone, an antidiabetic compound of the thiazolidinedione class, was reported to stimulate expression of a chimeric gene containing the enhancer/promoter of the lipid binding protein aP2 upstream of the chloroamphenicol acetyl transferase reporter gene (Harris and Kletzien, 1994, Mol. Pharmacol. 45:439 445). Deletion analysis led to the identification of an approximately 30 bp region accounting for pioglitazone responsiveness. In an independent study, this 30 bp fragment was shown to contain a PPRE (Tontonoz et al., 1994, Nucleic Acids Res. 22:5628 5634). Taken together, these studies suggested the possibility that the thiazolidinediones modulate gene expression at the transcriptional level through interactions with a PPAR and reinforce the concept of the interrelatedness of glucose and lipid metabolism.

2.5. Current Cholesterol Management Therapies

In the past two decades or so, the segregation of cholesterolemic compounds into HDL and LDL regulators and recognition of the desirability of decreasing blood levels of the latter has led to the development of a number of drugs. However, many of these drugs have undesirable side effects and/or are contraindicated in certain patients, particularly when administered in combination with other drugs.

Bile-acid-binding resins are a class of drugs that interrupt the recycling of bile acids from the intestine to the liver. Examples of bile-acid-binding resins are cholestyramine (QUESTRAN LIGHT, Bristol-Myers Squibb), and colestipol hydrochloride (COLESTID, Pharmacia & Upjohn Company). When taken orally, these positively charged resins bind to negatively charged bile acids in the intestine. Because the resins cannot be absorbed from the intestine, they are excreted, carrying the bile acids with them. The use of such resins, however, at best only lowers serum cholesterol levels by about 20%. Moreover, their use is associated with gastrointestinal side-effects, including constipation and certain vitamin deficiencies. Moreover, since the resins bind to drugs, other oral medications must be taken at least one hour before or four to six hours subsequent to ingestion of the resin, complicating heart patients' drug regimens.

The statins are inhibitors of cholesterol synthesis. Sometimes, the statins are used in combination therapy with bile-acid-binding resins. Lovastatin (MEVACOR, Merck & Co., Inc.), a natural product derived from a strain of Aspergillus; pravastatin (PRAVACHOL, Bristol-Myers Squibb Co.); and atorvastatin (LIPITOR, Warner Lambert) block cholesterol synthesis by inhibiting HMGCoA reductase, the key enzyme involved in the cholesterol biosynthetic pathway. Lovastatin significantly reduces serum cholesterol and LDL-serum levels. However, serum HDL levels are only slightly increased following lovastatin administration. The mechanism of the LDL-lowering effect may involve both reduction of VLDL concentration and induction of cellular expression of LDL-receptor, leading to reduced production and/or increased catabolism of LDL. Side effects, including liver and kidney dysfunction are associated with the use of these drugs.

Nicotinic acid, also known as niacin, is a water-soluble vitamin B-complex used as a dietary supplement and antihyperlipidemic agent. Niacin diminishes the production of VLDL and is effective at lowering LDL. It is used in combination with bile-acid-binding resins. Niacin can increase HDL when administered at therapeutically effective doses; however, its usefulness is limited by serious side effects.

Fibrates are a class of lipid-lowering drugs used to treat various forms of hyperlipidemia, elevated serum triglycerides, which may also be associated with hypercholesterolemia. Fibrates appear to reduce the VLDL fraction and modestly increase HDL; however, the effects of these drugs on serum cholesterol is variable. In the United States, fibrates have been approved for use as antilipidemic drugs, but have not received approval as hypercholesterolemia agents. For example, clofibrate (ATROMID-S, Wyeth-Ayerst Laboratories) is an antilipidemic agent that acts to lower serum triglycerides by reducing the VLDL fraction. Although ATROMID-S may reduce serum cholesterol levels in certain patient subpopulations, the biochemical response to the drug is variable, and is not always possible to predict which patients will obtain favorable results. ATROMID-S has not been shown to be effective for prevention of coronary heart disease. The chemically and pharmacologically related drug, gemfibrozil (LOPID, Parke-Davis), is a lipid regulating agent which moderately decreases serum triglycerides and VLDL cholesterol. LOPID also increases HDL cholesterol, particularly the HDL2 and HDL3 subfractions, as well as both the AI/AII-HDL fractions. However, the lipid response to LOPID is heterogeneous, especially among different patient populations. Moreover, while prevention of coronary heart disease was observed in male patients between the ages of 40 and 55 without history or symptoms of existing coronary heart disease, it is not clear to what extent these findings can be extrapolated to other patient populations (e.g., women, older and younger males). Indeed, no efficacy was observed in patients with established coronary heart disease. Serious side-effects are associated with the use of fibrates, including toxicity; malignancy, particularly malignancy of gastrointestinal cancer, gallbladder disease; and an increased incidence in non-coronary mortality. These drugs are not indicated for the treatment of patients with high LDL or low HDL as their only lipid abnormality.

Oral estrogen replacement therapy may be considered for moderate hypercholesterolemia in post-menopausal women. However, increases in HDL may be accompanied with an increase in triglycerides. Estrogen treatment is, of course, limited to a specific patient population, postmenopausal women, and is associated with serious side effects, including induction of malignant neoplasms; gall bladder disease; thromboembolic disease; hepatic adenoma; elevated blood pressure; glucose intolerance; and hypercalcemia.

Long chain carboxylic acids, particularly long chain .alpha.,.omega.-dicarboxylic acids with distinctive substitution patterns, and their simple derivatives and salts, have been disclosed for treating atherosclerosis, obesity, and diabetes (See, e.g., Bisgaier et al., 1998, J. Lipid Res. 39:17-30, and references cited therein; International Patent Publication WO 98/30530; U.S. Pat. No. 4,689,344; International Patent Publication WO 99/00116; and U.S. Pat. No. 5,756,344). However, some of these compounds, for example the .alpha.,.omega.-dicarboxylic acids substituted at their .alpha.,.alpha.'-carbons (U.S. Pat. No. 3,773,946), while having serum triglyceride and serum cholesterol-lowering activities, have no value for treatment of obesity and hypercholesterolemia (U.S. Pat. No. 4,689,344).

U.S. Pat. No. 4,689,344 discloses .beta.,.beta.,.beta.',.beta.'-tetrasubstituted-.alpha.,.omega.-alkanedioi- c acids that are optionally substituted at their .alpha.,.alpha.,.alpha.',.alpha.'-positions, and alleges that they are useful for treating obesity, hyperlipidemia, and diabetes. According to this reference, both triglycerides and cholesterol are lowered significantly by compounds such as 3,3,14,14-tetramethylhexadecane-1,16-dioic acid. U.S. Pat. No. 4,689,344 further discloses that the .beta.,.beta.,.beta.',.beta.'-tetramethyl-alkanediols of U.S. Pat. No. 3,930,024 also are not useful for treating hypercholesterolemia or obesity.

Other compounds are disclosed in U.S. Pat. No. 4,711,896. In U.S. Pat. No. 5,756,544, .alpha.,.omega.-dicarboxylic acid-terminated dialkane ethers are disclosed to have activity in lowering certain plasma lipids, including Lp(a), triglycerides, VLDL-cholesterol, and LDL-cholesterol, in animals, and elevating others, such as HDL-cholesterol. The compounds are also stated to increase insulin sensitivity. In U.S. Pat. No. 4,613,593, phosphates of dolichol, a polyprenol isolated from swine liver, are stated to be useful in regenerating liver tissue, and in treating hyperuricuria, hyperlipemia, diabetes, and hepatic diseases in general.

U.S. Pat. No. 4,287,200 discloses azolidinedione derivatives with anti-diabetic, hypolipidemic, and anti-hypertensive properties. However, the administration of these compounds to patients can produce side effects such as bone marrow depression, and both liver and cardiac cytotoxicity. Further, the compounds disclosed by U.S. Pat. No. 4,287,200 stimulate weight gain in obese patients.

It is clear that none of the commercially available cholesterol management drugs has a general utility in regulating lipid, lipoprotein, insulin and glucose levels in the blood. Thus, compounds that have one or more of these utilities are clearly needed. Further, there is a clear need to develop safer drugs that are efficacious at lowering serum cholesterol, increasing HDL serum levels, preventing coronary heart disease, and/or treating existing disease such as atherosclerosis, obesity, diabetes, and other diseases that are affected by lipid metabolism and/or lipid levels. There is also a clear need to develop drugs that may be used with other lipid-altering treatment regimens in a synergistic manner. There is still a further need to provide useful therapeutic agents whose solubility and Hydrophile/Lipophile Balance (HLB) can be readily varied.

The recitation of any reference in Section 2 of this application is not an admission that the reference is available as prior art to this application.

Scheme 1 illustrates the synthesis of mono-protected diols of the formula X, wherein n is an integer ranging from 0 to 4 and R.sup.1 and R.sup.2 are as defined above, and E is a leaving group as defined below. Scheme 1 first outlines the synthesis of mono-protected diols X, wherein n is 0, where esters 4 are successively reacted with a first ((R.sup.1).sub.p-M) then a second ((R.sup.2).sub.p-M) organometallic reagent providing ketones 5 and alcohols 6, respectively. M is a metal group and p is the metal's valency value (e.g., the valency of Li is 1 and that of Zn is 2). Suitable metals include, but are not limited to, Zn, Na, Li, and --Mg-Hal, wherein Hal is a halide selected from iodo, bromo, or chloro. Preferably, M is --Mg-Hal, in which case the organometallic reagents, (R.sup.1).sub.p--Mg-Hal and (R.sup.2).sub.p--Mg-Hal, are known in the art as a Grignard reagents.

Both (R.sup.1).sub.p-M and (R.sup.2).sub.p-M are available commercially (e.g., Aldrich Chemical Co., Milwaukee, Wis.) or can be prepared by well-known methods (see e.g., Kharasch et al., Grignard Reactions of Non-Metallic Substances; Prentice-Hall, Englewood Cliffs, N.J., pp. 138-528 (1954) and Hartley; Patai, The Chemistry of the Metal-Carbon Bond, Vol. 4, Wiley: New York, pp. 159-306 and pp. 162-175 (1989), both citations are hereby expressly incorporated herein by reference). The reaction of a first ((R.sup.1).sub.p-M) then a second ((R.sup.2).sub.p-M) organometallic reagent with esters 4 can be performed using the general procedures referenced in March, J. Advanced Organic Chemistry; Reactions Mechanisms, and Structure, 4th ed., 1992, pp. 920-929 and Eicher, Patai, The Chemistry of the Carbonyl Group, pt. 1, pp. 621-693; Wiley: New York, (1966), hereby expressly incorporated herein by reference. For example, the synthetic procedure described in Comins et al., 1981, Tetrahedron Lett. 22:1085, hereby expressly incorporated herein by reference, can be used. As one example, the reaction can be performed by adding an organic solution of (R.sup.1).sub.p-M (about 0.5 to about 1 equivalents) to a stirred, cooled (about 0.degree. C. to about -80.degree.

Next, an organic solution of (R.sup.2).sub.p-M (about 0.5 to about 1 equivalent) is added to the reaction mixture comprising ketones 5 in the same manner used to add (R.sup.1).sub.p-M. After the reaction providing alcohols 6 is substantially complete, the reaction mixture can be quenched and the product can be isolated by workup. Suitable solvents for obtaining alcohols 6 include, but are not limited to, dichloromethane, diethyl ether, tetrahydrofuran, benzene, toluene, xylene, hydrocarbon solvents (e.g., pentane, hexane, and heptane), and mixtures thereof.

Reaction of alcohols 6 with --O-PG under the conditions of the Williamson ether synthesis involves adding a base to a stirred organic solution comprising HO-PG (e.g., methoxymethanol), maintained at a constant temperature within the range of about 0.degree. C. to about 80.degree. C., preferably at about room temperature. Preferably, the base is added at a rate such that the reaction-mixture temperature remains within about one to two degrees of the initial reaction-mixture temperature. The base can be added as an organic solution or in undiluted form. Preferably, the base will have a base strength sufficient to deprotonate a proton, wherein the proton has a pK.sub.a of greater than about 15, preferably greater than about 20. As is well known in the art, the pK.sub.a is a measure of the acidity of an acid H-A, according to the equation pK.sub.a=-log K.sub.a, wherein K.sub.a is the equilibrium constant for the proton transfer. The acidity of an acid H-A is proportional to the stability of its conjugate base-A. For tables listing pK.sub.a values for various organic acids and a discussion on pK.sub.a measurement, see March, J. Advanced Organic Chemistry; Reactions Mechanisms, and Structure, 4th ed., 1992, pp. 248-272, incorporated herein by reference. Suitable bases include, but are not limited to, alkylmetal bases such as methyllithium, n-butyllithium, tert-butyllithium, sec-butyllithium, phenyllithium, phenyl sodium, and phenyl potassium; metal amide bases such as lithium amide, sodium amide, potassium amide, lithium tetramethylpiperidide, lithium diisopropylamide, lithium diethylamide, lithium dicyclohexylamide, sodium hexamethyldisilazide, and lithium hexamethyldisilazide; and hydride bases such as sodium hydride and potassium hydride. The preferred base is lithium diisopropylamide. Solvents suitable for reacting alcohols 6 with --OPG include, but are not limited, to dimethyl sulfoxide, dichloromethane, ethers, and mixtures thereof, preferably tetrahydrofuran. After addition of the base, the reaction mixture can be adjusted to within a temperature range of about 0.degree. C. to about room temperature and alcohols 6 can be added, preferably at a rate such that the reaction-mixture temperature remains within about one to two degrees of the initial reaction-mixture temperature. Alcohols 6 can be diluted in an organic solvent or added in their undiluted form. The resulting reaction mixture is stirred until the reaction is substantially complete as determined by using an appropriate analytical method, preferably by gas chromatography, then the mono-protected diols X can be isolated by workup and purification.

Next, Scheme I outlines a method useful for synthesizing mono-protected diols X, wherein n is 1. First, compounds 7, wherein E is a suitable leaving group, are reacted with compounds 8, wherein R.sup.1 and R.sup.2 are as defined above and R.sup.8 is H, (C.sub.1-C.sub.6)alkyl or (C.sub.6)aryl, providing compounds 9. Suitable leaving groups are well known in the art, for example, but not limited to halides, such as chloride, bromide, and iodide; aryl- or alkylsulfonyloxy, substituted arylsulfonyloxy (e.g., tosyloxy or mesyloxy); substituted alkylsulfonyloxy (e.g., haloalkylsulfonyloxy); (C.sub.6)aryloxy or substituted (C.sub.6)aryloxy; and acyloxy groups. Compounds 7 are available commercially (e.g., Aldrich Chemical Co., Milwaukee, Wis.) or can be prepared by well-known methods such as halogenation or sulfonation of butanediol. Compounds 8 are also available commercially (e.g., Aldrich Chemical Co., Milwaukee, Wis.) or by well-known methods, such as those listed in Larock Comprehensive Organic Transformations; Wiley-VCH: New York, 1999, pp. 1754-1755 and 1765. A review on alkylation of esters of type 8 is given by J. Mulzer in Comprehensive Organic Functional Transformations, Pergamon, Oxford 1995, pp. 148-151 and exemplary synthetic procedures for reacting compounds 7 with compounds 8 are described in U.S. Pat. No. 5,648,387, column 6 and Ackerly, et al., J. Med. Chem. 1995, pp. 1608, all of which citations are hereby expressly incorporated herein by reference. The reaction requires the presence of a suitable base. Preferably, a suitable base will have a pK.sub.a of greater than about 25, more preferably greater than about 30. Suitable bases include, but are not limited to, alkylmetal bases such as methyllithium, n-butyllithium, tert-butyllithium, sec-butyllithium, phenyllithium, phenyl sodium, and phenyl potassium; metal amide bases such as lithium amide, sodium amide, potassium amide, lithium tetramethylpiperidide, lithium diisopropylamide, lithium diethylamide, lithium dicyclohexylamide, sodium hexamethyldisilazide, and lithium hexamethyldisilazide; hydride bases such as sodium hydride and potassium hydride. Metal amide bases, such as lithium diisopropylamide are preferred. Preferably, to react compounds 7 with compounds 8, a solution of about 1 to about 2 equivalents of a suitable base is added to a stirred solution comprising esters 8 and a suitable organic solvent, under an inert atmosphere, the solution maintained at a constant temperature within the range of about -95.degree. C. to about room temperature, preferably at about -78.degree. C. to about -20.degree. C. Preferably, the base is diluted in a suitable organic solvent before addition. Preferably, the base is added at a rate of about 1.5 moles per hour. Organic solvents suitable for the reaction of compounds 7 with the compounds 8 include, but are not limited to, dichloromethane, diethyl ether, tetrahydrofuran, dimethylformamide, dimethyl sulfoxide, benzene, toluene, xylene, hydrocarbon solvents (e.g., pentane, hexane, and heptane), and mixtures thereof. After addition of the base, the reaction mixture is allowed to stir for about 1 to about 2 hours, and a compound 7, preferably dissolved in a suitable organic solvent, is added, preferably at a rate such that the reaction-mixture temperature remains within about one to two degrees of the initial reaction-mixture temperature. After addition of compounds 7, the reaction-mixture temperature can be adjusted to within a temperature range of about -20.degree. C. to about room temperature, preferably to about room temperature, and the reaction mixture is allowed to stir until the reaction is substantially complete as determined by using an appropriated analytical method, preferably thin-layer chromatography or high-performance liquid chromatography. Then the reaction mixture is quenched and compounds 9, wherein n is 1 can be isolated by workup. Compounds 10 are then synthesized by reacting compounds 9 with --O-PG according to the protocol described above for reacting alcohols 6 with --O-PG. Next, compounds 10 can be converted to mono-protected diols X, wherein n is 1, by reduction of the ester group of compounds 10 to an alcohol group with a suitable reducing agent. A wide variety of reagents are available for reduction of such esters to alcohols, e.g., see M. Hudlicky, Reductions in Organic Chemistry, 2nd ed., 1996 pp. 212-217, hereby expressly incorporated herein by reference. Preferably, the reduction is effected with a hydride type reducing agent, for example, lithium aluminum hydride, lithium borohydride, lithium triethyl borohydride, diisobutylaluminum hydride, lithium trimethoxyaluminum hydride, or sodium bis(2-methoxy)aluminum hydride. For exemplary procedures for reducing esters to alcohols, see Nystrom et al., 1947, J. Am. Chem. Soc. 69:1197; and Moffet et al., 1963, Org. Synth., Collect. 834(4), lithium aluminum hydride; Brown et al., 1965, J. Am. Chem. Soc. 87:5614, lithium trimethoxyaluminum hydride; Cerny et al., 1969, Collect. Czech. Chem. Commun. 34:1025, sodium bis(2-methoxy)aluminum hydride; Nystrom et al., 1949, J. Am. Chem. 71:245, lithium borohydride; and Brown et al., 1980, J. Org. Chem. 45:1, lithium triethyl borohydride, all of which citations are hereby expressly incorporated herein by reference. Preferably, the reduction is conducted by adding an organic solution of compounds 10 to a stirred mixture comprising a reducing agent, preferably lithium aluminum hydride, and an organic solvent. During the addition, the reaction mixture is maintained at a constant temperature within the range of about -20.degree. C. to about 80.degree. C., preferably at about room temperature. Organic solvents suitable for reacting 9 with --OPG include, but are not limited to, dichloromethane, diethyl ether, tetrahydrofuran or mixtures thereof, preferably tetrahydrofuran. After the addition, the reaction mixture is stirred at a constant temperature within the range of about room temperature to about 60.degree. C., until the reaction is substantially complete as determined by using an appropriate analytical method, preferably thin-layer chromatography or high-performance-liquid chromatography. Then the reaction mixture can be quenched and mono-protected diols X, wherein n is 1, can be isolated by workup and purification.

Scheme 1 next illustrates a three step synthetic sequence for homologating mono-protected diols X comprising: (a) halogenation (converting --CH.sub.2OH to --CH.sub.2-Hal); (b) carbonylation (replacing -Hal with --CHO); and (c) reduction (converting --CHO to --CH.sub.2OH), wherein a reaction sequence of (a), (b), and (c) increases the value of n by 1. In step (a) protected halo-alcohols 11, wherein Hal is a halide selected from the group of chloro, bromo, or iodo, preferably iodo, can be prepared by halogenating mono-protected diols X, by using well-known methods (for a discussion of various methods for conversion of alcohols to halides see March, J. Advanced Organic Chemistry; Reactions Mechanisms, and Structure, 4th ed., 1992, pp. 431-433, hereby expressly incorporated herein by reference). For example, protected iodo-alcohols 11 can be synthesized starting from mono-protected diols X by treatment with Ph.sub.3/I.sub.2/imidazole (Garegg et al., 1980, J. C. S Perkin I 2866); 1,2-dipheneylene phosphorochloridite/I.sub.2 (Corey et al., 1967, J. Org. Chem. 82:4160); or preferably with Me.sub.3SiCl/NaI (Olah et al., 1979, J. Org. Chem. 44:8, 1247), all of which citations are hereby expressly incorporated herein by reference. Step (b); carbonylation of alkyl halides, such as protected halo-alcohols 11, is reviewed in Olah et al., 1987, Chem Rev. 87:4, 671; and March, J., Advanced Organic Chemistry; Reactions Mechanisms, and Structure, 4th ed., 1992, pp. 483-484, both of which are hereby expressly incorporated herein by reference). Protected halo-alcohols 11 can be carbonylated with Li(BF.sub.3.Et.sub.2O)/HCONMe.sub.2 using the procedure described in Maddaford et al., 1993, J. Org. Chem. 58:4132; Becker et al., 1982, J. Org. Chem. 3297 or Myers et al., 1992, J. Am. Chem. Soc. 114:9369 or, alternatively, with an organometallic/N-formylmorpholine using the procedure described in Olah et al., 1984, J. Org. Chem. 49:3856 or Vogtle et al., 1987, J. Org. Chem. 52:5560, all of which citations are hereby expressly incorporated herein by reference. The method described in Olah et al., 1984, J. Org. Chem. 49:3856 is preferred. Reduction step (c) useful for synthesizing mono-protected diols X from aldehydes 12, can be accomplished by well-known methods in the art for reduction of aldehydes to the corresponding alcohols (for a discussion see M. Hudlicky, Reductions in Organic Chemistry, 2nd ed., 1996 pp 137-139), for example, by catalytic hydrogenation (see e.g., Carothers, 1949, J. Am. Chem. Soc. 46:1675) or, preferably by reacting aldehydes 12 with a hydride reducing agent, such as lithium aluminum hydride, lithium borohydride, sodium borohydride (see e.g., the procedures described in Chaikin et al., 1949, J. Am. Chem. Soc. 71:3245; Nystrom et al., 1947, J. Am. Chem. Soc. 69:1197; and Nystrom et al., 1949, J. Am. Chem. 71:3245, all of which are hereby expressly incorporated herein by reference). Reduction with lithium aluminum hydride is preferred.

Scheme 2 outlines the method for the synthesis of protected alcohols 12a wherein Y, R.sup.1, R.sup.2, Z, and m are defined as above. Protected alcohols 12a correspond to compounds of the formula W.sup.(1)(2)-Zm-OPG, wherein W.sup.(1)(2) is C(R.sup.1)(R.sup.2)--Y.

Protected alcohols 16, wherein Y comprises a --C(O)OH group, can be synthesized by oxidizing mono-protected diols X with an agent suitable for oxidizing a primary alcohol to a carboxylic acid (for a discussion see M. Hudlicky, Oxidations in Organic Chemistry, ACS Monograph 186, 1990, pp. 127-130, hereby expressly incorporated herein by reference). Suitable oxidizing agents include, but are not limited to, pyridinium dichromate (Corey et al., 1979, Tetrahedron Lett. 399); manganese dioxide (Ahrens et al., 1967, J. Heterocycl. Chem. 4:625); sodium permanganate monohydrate (Menger et al., 1981, Tetrahedron Lett. 22:1655); and potassium permanganate (Sam et al., 1972, J. Am. Chem. Soc. 94:4024), all of which citations are hereby expressly incorporated herein by reference. The preferred oxidizing reagent is pyridinium dichromate. In an alternative synthetic procedure, protected alcohols 16, wherein Y comprises a --C(O)OH group, can be synthesized by treatment of protected halo-alcohols 15, wherein X is iodo, with CO or CO.sub.2, as described in Bailey et al., 1990, J. Org. Chem. 55:5404 and Yanagisawa et al., 1994, J. Am. Chem. Soc. 116:6130, the two of which citations are hereby expressly incorporated herein by reference. Protected alcohols 16, wherein Y comprises --C(O)OR.sup.5, wherein R.sup.5 is as defined above, can be synthesized by oxidation of mono-protected diols X in the presence of R.sup.5OH (see generally, March, J. Advanced Organic Chemistry; Reactions Mechanisms, and Structure, 4th ed., 1992, p. 1196). An exemplary procedure for such an oxidation is described in Stevens et al., 1982, Tetrahedron Lett. 23:4647 (HOCl); Sundararaman et al., 1978, Tetrahedron Lett. 1627 (O.sub.3/KOH); Wilson et al., 1982, J. Org. Chem. 47:1360 (t-BuOOH/Et.sub.3N); and Williams et al., 1988, Tetrahedron Lett. 29:5087 (Br.sub.2), the four of which citations are hereby expressly incorporated herein by reference. Preferably, protected alcohols 16, wherein Y comprises a --C(O)OR.sup.5 group are synthesized from the corresponding carboxylic acid (i.e., 16, wherein Y comprises --C(O)OH) by esterification with R.sup.5OH (e.g., see March, J., Advanced Organic Chemistry; Reactions Mechanisms, and Structure, 4th ed., 1992, p. 393-394, hereby expressly incorporated herein by reference). In another alternative synthesis, protected alcohols 16, wherein Y comprises --C(O)OR.sup.5, can be prepared from protected halo-alcohols 14 by carbonylation with transition metal complexes (see e.g., March, J. Advanced Organic Chemistry; Reactions Mechanisms, and Structure, 4th ed., 1992, p. 484-486; Urata et al., 1991, Tetrahedron Lett. 32:36, 4733); and Ogata et al., 1969, J. Org. Chem. 3985, the three of which citations are hereby expressly incorporated herein by reference).

Protected alcohols 16, wherein Y comprises --OC(O)R.sup.5, wherein R.sup.5 is as defined above, can be prepared by acylation of mono-protected diols X with a carboxylate equivalent such as an acyl halide (i.e., R.sup.5C(O)-Hal, wherein Hal is iodo, bromo, or chloro, see e.g., March, J. Advanced Organic Chemistry; Reactions Mechanisms, and Structure, 4th ed., 1992, p. 392 and Org. Synth. Coll. Vol. III, Wiley, N.Y., pp. 142, 144, 167, and 187 (1955)) or an anhydride (i.e., R.sup.5C(O)--O--(O)CR.sup.5, see e.g., March, J. Advanced Organic Chemistry; Reactions Mechanisms, and Structure, 4th ed., 1992, p. 392-393 and Org. Synth. Coll. Vol. III, Wiley, N.Y., pp. 11, 127, 141, 169, 237, 281, 428, 432, 690, and 833 (1955), all of which citations are hereby expressly incorporated herein by reference). Preferably, the reaction is conducted by adding a base to a solution comprising mono-protected diols X, a carboxylate equivalent, and an organic solvent, which solution is preferably maintained at a constant temperature within the range of 0.degree. C. to about room temperature. Solvents suitable for reacting mono-protected diols X with a carboxylate equivalent include, but are not limited to, dichloromethane, toluene, and ether, preferably dichloromethane. Suitable bases include, but are not limited to, hydroxide sources, such as sodium hydroxide, potassium hydroxide, sodium carbonate, or potassium carbonate; or an amine such as triethylamine, pyridine, or dimethylaminopyridine, amines are preferred. The progress of the reaction can be followed by using an appropriate analytical technique, such as thin layer chromatography or high performance liquid chromatography and when substantially complete, the product can be isolated by workup and purified if desired.

Protected alcohols 16, wherein Y comprises one of the following phosphate ester groups

##STR00459## wherein R.sup.6 is defined as above, can be prepared by phosphorylation of mono-protected diols X according to well-known methods (for a general reviews, see Corbridge Phosphorus: An Outline of its Chemistry, Biochemistry, and Uses, Studies in Inorganic Chemistry, 3rd ed., pp. 357-395 (1985); Ramirez et al., 1978, Acc. Chem. Res. 11:239; and Kalckare Biological Phosphorylations, Prentice-Hall, New York (1969); J. B. Sweeny in Comprehensive Organic Functional Group Transformations, A. R. Katritzky, O. Meth-Cohn and C. W. Rees, Eds. Pergamon: Oxford, 1995, vol 2, pp. 104-109, the four of which are hereby expressly incorporated herein by reference). Protected alcohols 16 wherein Y comprises a monophosphate group of the formula:

##STR00460## wherein R.sup.6 is defined as above, can be prepared by treatment of mono-protected diol X with phosphorous oxychloride in a suitable solvent, such as xylene or toluene, at a constant temperature within the range of about 100.degree. C. to about 150.degree. C. for about 2 hours to about 24 hours. After the reaction is deemed substantially complete, by using an appropriate analytical method, the reaction mixture is hydrolyzed with R.sup.10H. Suitable procedures are referenced in Houben-Weyl, Methoden der Organische Chemie, Georg Thieme Verlag Stuttgart 1964, vol. XII/2, pp. 143-210 and 872-879, hereby expressly incorporated herein by reference. Alternatively, when both R.sup.6 are hydrogen, can be synthesized by reacting mono-protected diols X with silyl polyphosphate (Okamoto et al., 1985, Bull Chem. Soc. Jpn. 58:3393, hereby expressly incorporated herein by reference) or by hydrogenolysis of their benzyl or phenyl esters (Chen et al., 1998, J. Org. Chem. 63:6511, hereby expressly incorporated herein by reference). In another alternative procedure, when R.sup.6 is (C.sub.1-C.sub.6)alkyl, (C.sub.2-C.sub.6)alkenyl, or (C.sub.2-C.sub.6)alkynyl, the monophosphate esters can be prepared by reacting mono-protected diols X with appropriately substituted phosphoramidites followed by oxidation of the intermediate with m-chloroperbenzoic acid (Yu et al., 1988, Tetrahedron Lett. 29:979, hereby expressly incorporated herein by reference) or by reacting mono-protected diols X with dialkyl or diaryl substituted phosphorochloridates (Pop, et al, 1997, Org. Prep. and Proc. Int. 29:341, hereby expressly incorporated herein by reference). The phosphoramidites are commercially available (e.g., Aldrich Chemical Co., Milwaukee, Wis.) or readily prepared according to literature procedures (see e.g., Uhlmann et al. 1986, Tetrahedron Lett. 27:1023 and Tanaka et al., 1988, Tetrahedron Lett. 29:199, both of which are hereby expressly incorporated herein by reference). The phosphorochloridates are also commercially available (e.g., Aldrich Chemical Co., Milwaukee, Wis.) or prepared according to literature methods (e.g., Gajda et al, 1995, Synthesis 25:4099. In still another alternative synthesis, protected alcohols 16, wherein Y comprises a monophosphate group and R.sup.6 is alkyl or aryl, can be prepared by reacting IP.sup.+(OR.sup.6).sub.3 with mono-protected diols X according to the procedure described in Stowell et al., 1995, Tetrahedron Lett. 36:11, 1825 or by alkylation of protected halo alcohols 14 with the appropriate dialkyl or diaryl phosphates (see e.g., Okamoto, 1985, Bull Chem. Soc. Jpn. 58:3393, hereby expressly incorporated herein by reference).

Protected alcohols 16 wherein Y comprises a diphosphate group of the formula

##STR00461## wherein R.sup.6 is defined as above, can be synthesized by reacting the above-discussed monophosphates of the formula:

##STR00462## with a phosphate of the formula

##STR00463## (commercially available, e.g., Aldrich Chemical Co., Milwaukee, Wis.), in the presence of carbodiimide such as dicyclohexylcarbodiimide, as described in Houben-Weyl, Methoden der Organische Chemie, Georg Thieme Verlag Stuttgart 1964, vol. XII/2, pp. 881-885. In the same fashion, protected alcohols 16, wherein Y comprises a triphosphate group of the formula:

##STR00464## can be synthesized by reacting the above-discussed diphosphate protected alcohols, of the formula:

##STR00465## with a phosphate of the formula:

##STR00466## as described above. Alternatively, when R.sup.6 is H, protected alcohols 16 wherein Y comprises the triphosphate group, can be prepared by reacting mono-protected diols X with salicyl phosphorochloridite and then pyrophosphate and subsequent cleavage of the adduct thus obtained with iodine in pyridine as described in Ludwig et al., 1989, J. Org. Chem. 54:631, hereby expressly incorporated herein by reference.

Protected alcohols 16, wherein Y is --SO.sub.3H or a heterocyclic group selected from the group consisting of:

##STR00467## can be prepared by halide displacement from protected halo-alcohols 14. Thus, when Y is --SO.sub.3H, protected alcohols 16 can by synthesized by reacting protected halo-alcohols 14 with sodium sulfite as described in Gilbert Sulfonation and Related Reactions; Wiley: New York, 1965, pp. 136-148 and pp. 161-163; Org. Synth. Coll. Vol. II, Wiley, N.Y., 558, 564 (1943); and Org. Synth. Coll. Vol. IV, Wiley, N.Y., 529 (1963), all three of which are hereby expressly incorporated herein by reference. When Y is one of the above-mentioned heterocycles, protected alcohols 16 can be prepared by reacting protected halo-alcohols 14 with the corresponding heterocycle in the presence of a base. The heterocycles are available commercially (e.g., Aldrich Chemical Co., Milwaukee, Wis.) or prepared by well-known synthetic methods (see the procedures described in Ware, 1950, Chem. Rev. 46:403-470, hereby expressly incorporated herein by reference). Preferably, the reaction is conducted by stirring a mixture comprising 14, the heterocycle, and a solvent at a constant temperature within the range of about room temperature to about 100.degree. C., preferably within the range of about 50.degree. C. to about 70.degree. C. for about 10 to about 48 hours. Suitable bases include hydroxide bases such as sodium hydroxide, potassium hydroxide, sodium carbonate, or potassium carbonate. Preferably, the solvent used in forming protected alcohols 16 is selected from dimethylformamide; formamide; dimethyl sulfoxide; alcohols, such as methanol or ethanol; and mixtures thereof. The progress of the reaction can be followed by using an appropriate analytical technique, such as thin layer chromatography or high performance liquid chromatography and when substantially complete, the product can be isolated by workup and purified if desired.

Protected alcohols 16, wherein Y is a heteroaryl ring selected from

##STR00468## can be prepared by metallating the suitable heteroaryl ring then reacting the resulting metallated heteroaryl ring with protected halo-alcohols 14 (for a review, see Katritzky Handbook of Heterocyclic Chemistry, Pergamon Press: Oxford 1985). The heteroaryl rings are available commercially or prepared by well-known synthetic methods (see e.g., Joule et al., Heterocyclic Chemistry, 3rd ed., 1995; De Sarlo et al., 1971, J. Chem. Soc. (C) 86; Oster et al., 1983, J. Org. Chem. 48:4307; Iwai et al., 1966, Chem. Pharm. Bull. 14:1277; and U.S. Pat. No. 3,152,148, all of which citations are hereby expressly incorporated herein by reference). As used herein, the term "metallating" means the forming of a carbon-metal bond, which bond may be substantially ionic in character. Metallation can be accomplished by adding about 2 equivalents of strong organometallic base, preferably with a pK.sub.a of about 25 or more, more preferably with a pK.sub.a of greater than about 35, to a mixture comprising a suitable organic solvent and the heterocycle. Two equivalents of base are required: one equivalent of the base deprotonates the --OH group or the --NH group, and the second equivalent metallates the heteroaryl ring. Alternatively, the hydroxy group of the heteroaryl ring can be protected with a base-stable, acid-labile protecting group as described in Greene, T. W., Protective Groups in Organic Synthesis, 3rd edition 17-237 (1999), hereby expressly incorporated herein by reference. Where the hydroxy group is protected, only one equivalent of base is required. Examples of suitable base-stable, acid-labile hydroxyl-protecting groups, include but are not limited to, ethers, such as methyl, methoxy methyl, methylthiomethyl, methoxyethoxymethyl, bis(2-chloroethoxy)methyl, tetrahydropyranyl, tetrahydrothiopyranyl; tetrahydrofuranyl, tetrahydrothiofuranyl, 1-ethoxyethyl, 1-methyl-1-methoxyethyl, t-butyl, allyl, benzyl, o-nitrobenzyl, triphenylmethyl, x-naphthyldiphenylmethyl, p-methoxyphenyldiphenylmethyl, 9-(9-phenyl-10-oxo)anthranyl, trimethylsilyl, isopropyldimethylsilyl, t-butyldimethylsilyl, t-butyldiphenylsilyl, tribenzylsilyl, triisopropylsilyl; and esters, such as pivaloate, adamantoate, and 2,4,6-trimethylbenzoate. Ethers are preferred, particularly straight chain ethers, such as methyl ether, methoxymethyl ether, methylthiomethyl ether, methoxyethoxymethyl ether, bis(2-chloroethoxy)methyl ether. Preferably, the pK.sub.a of the base is higher than the pK.sub.a of the proton of the heterocycle to be deprotonated. For a listing of pK.sub.as for various heteroaryl rings, see Fraser et al., 1985, Can. J. Chem. 63:3505, hereby expressly incorporated herein by reference. Suitable bases include, but are not limited to, alkylmetal bases such as methyllithium, n-butyllithium, tert-butyllithium, sec-butyllithium, phenyllithium, phenyl sodium, and phenyl potassium; metal amide bases such as lithium amide, sodium amide, potassium amide, lithium tetramethylpiperidide, lithium diisopropylamide, lithium diethylamide, lithium dicyclohexylamide, sodium hexamethyldisilazide, and lithium hexamethyldisilazide; and hydride bases such as sodium hydride and potassium hydride. If desired, the organometallic base can be activated with a complexing agent, such as N,N,N',N'-tetramethylethylenediamine or hexamethylphosphoramide (1970, J. Am. Chem. Soc. 92:4664, hereby expressly incorporated herein by reference). Solvents suitable for synthesizing protected alcohols 16, wherein Y is a heteroaryl ring include, but are not limited to, diethyl ether; tetrahydrofuran; and hydrocarbons, such as pentane. Generally, metallation occurs alpha to the heteroatom due to the inductive effect of the heteroatom, however, modification of conditions, such as the identity of the base and solvents, order of reagent addition, reagent addition times, and reaction and addition temperatures can be modified by one of skill in the art to achieve the desired metallation position (see e.g., Joule et al., Heterocyclic Chemistry, 3rd ed., 1995, pp. 30-42, hereby expressly incorporated herein by reference) Alternatively, the position of metallation can be controlled by use of a halogenated heteroaryl group, wherein the halogen is located on the position of the heteroaryl ring where metallation is desired (see e.g., Joule et al., Heterocyclic Chemistry, 3rd ed., 1995, p. 33 and Saulnier et al., 1982, J.

Halogenated heteroaryl groups are available commercially (e.g., Aldrich Chemical Co., Milwaukee, Wis.) or can be prepared by well-known synthetic methods (see e.g., Joule et al., Heterocyclic Chemistry, 3rd ed., 1995, pp. 78, 85, 122, 193, 234, 261, 280, 308, hereby expressly incorporated herein by reference). After metallation, the reaction mixture comprising the metallated heteroaryl ring is adjusted to within a temperature range of about 0.degree. C. to about room temperature and protected halo-alcohols 14 (diluted with a solvent or in undiluted form) are added, preferably at a rate such that the reaction-mixture temperature remains within about one to two degrees of the initial reaction-mixture temperature. After addition of protected halo-alcohols 14, the reaction mixture is stirred at a constant temperature within the range of about room temperature and about the solvent's boiling temperature and the reaction's progress can be monitored by the appropriate analytical technique, preferably thin-layer chromatography or high-performance liquid chromatography. After the reaction is substantially complete, protected alcohols 16 can be isolated by workup and purification. It is to be understood that conditions, such as the identity of protected halo-alcohol 14, the base, solvents, orders of reagent addition, times, and temperatures, can be modified by one of skill in the art to optimize the yield and selectivity. Exemplary procedures that can be used in such a transformation are described in Shirley et al., 1995, J. Org. Chem. 20:225; Chadwick et al., 1979, J. Chem.

Scheme 4 outlines methodology for the synthesis of protected alcohols 14. Compounds 14, wherein n is an integer ranging from 1 to 5, can be prepared from compounds 11 using general synthetic strategy depicted and adapting the synthetic protocols from those discussed for Scheme 1.

Next, Scheme 4 depicts the general strategy for the synthesis of compounds 14 wherein n is 0. First, Esters 27, wherein R.sup.8 is as defined above, are synthesized by oxidation of mono-protected diols X in the presence of R.sup.8OH (see generally, March, J. Advanced Organic Chemistry; Reactions Mechanisms, and Structure, 4th ed., 1992, p. 1196). An exemplary procedure for such an oxidation is described in Stevens et al., 1982, Tetrahedron Lett. 23:4647 (HOCl); Sundararaman et al., 1978, Tetrahedron Lett. 1627 (O.sub.3/KOH); Wilson et al., 1982, J.

##STR00486## As shown in Scheme 6, protected lactone alcohols 30 and lactone alcohols 16a can be synthesized from compounds of the formula X, 11, or 12 by adaptation of the methods and procedures discussed above for Scheme 3.

##STR00487##

Scheme 7 depicts the synthesis of halides 17. Halides 17 can be synthesized by a variety of methods. One method involves conversion of the alcohol to a leaving group such as a sulfonic ester, such as, for example, tosylate, brosylate, mesylate, or nosylate. This intermediate is then treated with a source of X.sup.-, wherein X.sup.- is I.sup.-, Br.sup.-, or Cl.sup.- in a solvent such as THF or ether. A general method for converting vinyl and phenyl alcohols to thiols involves initially converting the alcohol to a leaving group (e.g., a tosylate) then treating with a halide nucleophile.

##STR00488##

Scheme 8 outlines the synthesis of compounds I. In the first step, compounds I are synthesized by reacting compounds 17 (compounds X 11, 12, 13, 14, 15, and 16 are encompassed by 17) with compounds 31 under the conditions suitable for the formation of compounds I. The conditions and methods discussed in Scheme 1 above for the synthesis of mono-protected diols X from alcohols 6 can be adapted for the synthesis of compounds 17. Compounds 31, wherein Y is a suitable leaving group as defined above, preferably an anhydride, an ester, or an amide group, are readily obtained commercially (e.g., Aldrich Chemical Co. Milwaukee Wis.) or by well known synthetic methods. Compounds I are obtained by reacting compounds 31 with compounds 17 under the conditions suitable for alkyl-de-acyloxy substitution. (For a review, See Kharasch; Reinmuth, Grignard Reactions of Nonmetallic Substances; Prentice Hall: Englewood Cliffs, N.J., 1954, pp. 561-562 and 846-908. In a preferred procedure, the conversion of anhydrides, carboxylic esters, or amides to ketones with organometallic compounds. In a particular procedure, anhydrides and carboxylic esters give ketones when treated using inverse addition of Grignard reagents at low temperature with the solvent HMPA. See Newman, J. Org. Chem. 1948, 13, 592; Huet; Empotz; Jubier Tetrahedron 1973, 29, 479; and Comprehensive Organic Transformations; VCH: New York, 1989, pp. 685-686, 693-700. Ketones can also be prepare by the treatment of thioamides with organolithium compounds (alkyl or aryl). See Tominaga; Kohra; Hosomi Tetrahedron Lett. 1987, 28, 1529. Moreover, alkyllithium compounds have been used to give ketones from carboxylic esters. See Petrov; Kaplan; Tsir J. Gen. Chem. USSR 1962, 32, 691. The reaction must be carried out in a high-boiling solvent such as toluene. Di-substituted amides also can be used to synthesize ketones. See Evans J. Chem. Soc. 1956, 4691; and Wakefield Organolithium Methods; Academic Press: New York, 1988, pp. 82-88.

Scheme 9 illustrates the alpha disubstitution of an ester containing a terminal protected hydroxyl moiety. Compounds that contain strong electron withdrawing groups are easily converted to the corresponding enolates. These enolate ions can readilt attack an electrophile resulting in alpha substitution. See Some Modern Methods of Organic Synthesis, 3.sup.rd Ed.; Cambridge University Press: Cambridge, 1986, pp. 1-26, hereby expressly incorporated herein by reference. The reaction is successful for primary and secondary alkyl, allylic, and benzylic. The use of polar aprotic solvents, e.g., dimethylformamide or dimethylsulfoxide, are preferred. Phase transfer catalysts can also be used. See Tundo et al. J. Chem. Soc., Perkin Trans. 1, 1987, 2159, which is hereby expressly incorporated herein by reference.

The conversion to a carboxylic acid with an additional carbon is achieved by treating an acyl halide with diazomethane to generate an intermediate diazo ketone, which in the presence of water and silver oxide rearranges through a ketene intermediate to a carboxylic acid with an additional carbon atom 37. If the reaction is done in an alcohol instead of water an ester is recovered. See Meier et al. Angew. Chem. Int. Ed. Eng. 1975, 14, 32-43, which is hereby expressly incorporated herein by reference. Alternatively, the carboxylic acid can be esterified by known techniques. The reaction can be repeated to generate methylene groups adjacent to the carboxylic acid.

In another alternative procedure, when R.sup.6 is (C.sub.1-C.sub.6)alkyl, (C.sub.2-C.sub.6)alkenyl, or (C.sub.2-C.sub.6)alkynyl, the monophosphate esters can be prepared by reacting mono-protected diols 39 with appropriately substituted phosphoramidites followed by oxidation of the intermediate with m-chloroperbenzoic acid (Yu et al., 1988, Tetrahedron Lett. 29:979, incorporated herein by reference) or by reacting mono-protected diols 39 with dialkyl or diaryl substituted phosphorochloridates (Pop, et al, 1997, Org. Prep. and Proc. Int. 29:341, incorporated herein by reference). The phosphoramidites are commercially available (e.g., Aldrich Chemical Co., Milwaukee, Wis.) or readily prepared according to literature procedures (see e.g., Uhlmann et al. 1986, Tetrahedron Lett. 27:1023 and Tanaka et al., 1988, Tetrahedron Lett. 29:199, both of which are incorporated herein by reference). The phosphorochloridates are also commercially available (e.g., Aldrich Chemical Co., Milwaukee, Wis.) or prepared according to literature methods (e.g., Gajda et al, 1995, Synthesis 25:4099. In still another alternative synthesis, protected alcohols 42, wherein Y comprises a monophosphate group and R.sup.6 is alkyl or aryl, can be prepared by reacting IP.sup.+(OR.sup.6).sub.3 with mono-protected diols 39 according to the procedure described in Stowell et al., 1995, Tetrahedron Lett. 36:11, 1825 or by alkylation of protected halo alcohols 40 with the appropriate dialkyl or diaryl phosphates (see e.g., Okamoto, 1985, Bull Chem. Soc. Jpn. 58:3393, incorporated herein by reference).

Protected alcohols 42 wherein Y comprises a diphosphate group of the formula

##STR00493## wherein R.sup.6 is defined as above, can be synthesized by reacting the above-discussed monophosphates of the formula:

##STR00494## with a phosphate of the formula

##STR00495## (commercially available, e.g., Aldrich Chemical Co., Milwaukee, Wis.), in the presence of carbodiimide such as dicyclohexylcarbodiimide, as described in Houben-Weyl, Methoden der Organische Chemie, Georg Thieme Verlag Stuttgart 1964, vol. XII/2, pp. 881-885. In the same fashion, protected alcohols 42, wherein Y comprises a triphosphate group of the formula:

##STR00496## can be synthesized by reacting the above-discussed diphosphate protected alcohols, of the formula:

##STR00497## with a phosphate of the formula:

##STR00498## as described above. Alternatively, when R.sup.6 is H, protected alcohols 42 wherein Y comprises the triphosphate group, can be prepared by reacting mono-protected diols 39 with salicyl phosphorochloridite and then pyrophosphate and subsequent cleavage of the adduct thus obtained with iodine in pyridine as described in Ludwig et al., 1989, J. Org. Chem. 54:631, incorporated herein by reference.

Protected alcohols 42, wherein Y is --SO.sub.3H or a heterocyclic group selected from the group consisting of:

##STR00499## can be prepared by halide displacement from protected halo-alcohols 40. Thus, when Y is --SO.sub.3H, protected alcohols 42 can by synthesized by reacting protected halo-alcohols with sodium sulfite as described in Gilbert Sulfonation and Related Reactions; Wiley: New York, 1965, pp. 136-148 and pp. 161-163; Org. Synth. Coll. Vol. II, Wiley, N.Y., 558, 564 (1943); and Org. Synth. Coll. Vol. IV, Wiley, N.Y., 529 (1963), all three of which are incorporated herein by reference. When Y is one of the above-mentioned heterocycles, protected alcohols 42 can be prepared by reacting protected halo-alcohols with the corresponding heterocycle in the presence of a base. The heterocycles are available commercially (e.g., Aldrich Chemical Co., Milwaukee, Wis.) or prepared by well-known synthetic methods (see the procedures described in Ware, 1950, Chem. Rev. 46:403-470, incorporated herein by reference). Preferably, the reaction is conducted by stirring a mixture comprising 40, the heterocycle, and a solvent at a constant temperature within the range of about room temperature to about 100.degree. C., preferably within the range of about 50.degree. C. to about 70.degree. C. for about 10 to about 48 hours. Suitable bases include hydroxide bases such as sodium hydroxide, potassium hydroxide, sodium carbonate, or potassium carbonate. Preferably, the solvent used in forming protected alcohols 42 is selected from dimethylformamide; formamide; dimethyl sulfoxide; alcohols, such as methanol or ethanol; and mixtures thereof. The progress of the reaction can be followed by using an appropriate analytical technique, such as thin layer chromatography or high performance liquid chromatography and when substantially complete, the product can be isolated by workup and purified if desired.

Protected alcohols 42, wherein Y is a heteroaryl ring selected from

##STR00500## can be prepared by metallating the suitable heteroaryl ring then reacting the resulting metallated heteroaryl ring with protected halo-alcohols 40 (for a review, see Katritzky Handbook of Heterocyclic Chemistry, Pergamon Press: Oxford 1985). The heteroaryl rings are available commercially or prepared by well-known synthetic methods (see e.g., Joule et al., Heterocyclic Chemistry, 3rd ed., 1995; De Sarlo et al., 1971, J. Chem. Soc. (C) 86; Oster et al., 1983, J. Org. Chem. 48:4307; Iwai et al., 1966, Chem. Pharm. Bull. 14:1277; and U.S. Pat. No. 3,152,148, all of which citations are incorporated herein by reference). As used herein, the term "metallating" means the forming of a carbon-metal bond, which bond may be substantially ionic in character. Metallation can be accomplished by adding about 2 equivalents of strong organometallic base, preferably with a pK.sub.a of about 25 or more, more preferably with a pK.sub.a of greater than about 35, to a mixture comprising a suitable organic solvent and the heterocycle. Two equivalents of base are required: one equivalent of the base deprotonates the --OH group or the --NH group, and the second equivalent metallates the heteroaryl ring. Alternatively, the hydroxy group of the heteroaryl ring can be protected with a base-stable, acid-labile protecting group as described in Greene, T. W., Protective Groups in Organic Synthesis, 3rd edition 17-237 (1999), hereby expressly incorporated herein by reference. Where the hydroxy group is protected, only one equivalent of base is required. Examples of suitable base-stable, acid-labile hydroxyl-protecting groups, include but are not limited to, ethers, such as methyl, methoxy methyl, methylthiomethyl, methoxyethoxymethyl, bis(2-chloroethoxy)methyl, tetrahydropyranyl, tetrahydrothiopyranyl, tetrahydrofuranyl, tetrahydrothiofuranyl, 1-ethoxyethyl, 1-methyl-1-methoxyethyl, t-butyl, allyl, benzyl, o-nitrobenzyl, triphenylmethyl, .alpha.-naphthyldiphenylmethyl, p-methoxyphenyldiphenylmethyl, 9-(9-phenyl-10-oxo)anthranyl, trimethylsilyl, isopropyldimethylsilyl, t-butyldimethylsilyl, t-butyldiphenylsilyl, tribenzylsilyl, triisopropylsilyl; and esters, such as pivaloate, adamantoate, and 2,4,6-trimethylbenzoate. Ethers are preferred, particularly straight chain ethers, such as methyl ether, methoxymethyl ether, methylthiomethyl ether, methoxyethoxymethyl ether, bis(2-chloroethoxy)methyl ether. Preferably, the pK.sub.a of the base is higher than the pK.sub.a of the proton of the heterocycle to be deprotonated. For a listing of pK.sub.as for various heteroaryl rings, see Fraser et al., 1985, Can. J. Chem. 63:3505, incorporated herein by reference. Suitable bases include, but are not limited to, alkylmetal bases such as methyllithium, n-butyllithium, tert-butyllithium, sec-butyllithium, phenyllithium, phenyl sodium, and phenyl potassium; metal amide bases such as lithium amide, sodium amide, potassium amide, lithium tetramethylpiperidide, lithium diisopropylamide, lithium diethylamide, lithium dicyclohexylamide, sodium hexamethyldisilazide, and lithium hexamethyldisilazide; and hydride bases such as sodium hydride and potassium hydride. If desired, the organometallic base can be activated with a complexing agent, such as N,N,N',N'-tetramethylethylenediamine or hexamethylphosphoramide (1970, J. Am. Chem. Soc. 92:4664, hereby expressly incorporated herein by reference). Solvents suitable for synthesizing protected alcohols 42, wherein Y is a heteroaryl ring include, but are not limited to, diethyl ether, tetrahydrofuran; and hydrocarbons, such as pentane. Generally, metallation occurs alpha to the heteroatom due to the inductive effect of the heteroatom, however, modification of conditions, such as the identity of the base and solvents, order of reagent addition, reagent addition times, and reaction and addition temperatures can be modified by one of skill in the art to achieve the desired metallation position (see e.g., Joule et al., Heterocyclic Chemistry, 3rd ed., 1995, pp. 30-42, hereby expressly incorporated herein by reference) Alternatively, the position of metallation can be controlled by use of a halogenated heteroaryl group, wherein the halogen is located on the position of the heteroaryl ring where metallation is desired (see e.g., Joule et al., Heterocyclic Chemistry, 3rd ed., 1995, p. 33 and Saulnier et al., 1982, J. Org. Chem. 47:757, the two of which citations are hereby expressly incorporated herein by reference). Halogenated heteroaryl groups are available commercially (e.g., Aldrich Chemical Co., Milwaukee, Wis.) or can be prepared by well-known synthetic methods (see e.g., Joule et al., Heterocyclic Chemistry, 3rd ed., 1995, pp. 78, 85, 122, 193, 234, 261, 280, 308, hereby expressly incorporated herein by reference). After metallation, the reaction mixture comprising the metallated heteroaryl ring is adjusted to within a temperature range of about 0.degree. C. to about room temperature and protected halo-alcohols 40 (diluted with a solvent or in undiluted form) are added, preferably at a rate such that the reaction-mixture temperature remains within about one to two degrees of the initial reaction-mixture temperature. After addition of protected halo-alcohols 40, the reaction mixture is stirred at a constant temperature within the range of about room temperature and about the solvent's boiling temperature and the reaction's progress can be monitored by the appropriate analytical technique, preferably thin-layer chromatography or high-performance liquid chromatography. After the reaction is substantially complete, protected alcohols 42 can be isolated by workup and purification. It is to be understood that conditions, such as the identity of protected halo-alcohol 40, the base, solvents, orders of reagent addition, times, and temperatures, can be modified by one of skill in the art to optimize the yield and selectivity. Exemplary procedures that can be used in such a transformation are described in Shirley et al., 1995, J. Org. Chem. 20:225; Chadwick et at., 1979, J. Chem. Soc., Perkin Trans. 1 2845; Rewcastle, 1993, Adv. Het. Chem. 56:208; Katritzky et al., 1993, Adv. Het. Chem. 56:155; and Kessar et al., 1997, Chem. Rev. 97:721. When Y is

##STR00501## protected alcohols 42 can be prepared from their corresponding carboxylic acid derivatives (42, wherein Y is --CO.sub.2H) as described in Belletire et al. 1988, Synthetic Commun. 18:2063 or from the corresponding acylchlorides (42, wherein Y is --CO-halo) as described in Skinner et al., 1995, J. Am. Chem. Soc. 277:5440, both citations are incorporated herein by reference. The acylhalides can be prepared from the carboxylic acids by well known procedures such as those described in March, J., Advanced Organic Chemistry; Reactions Mechanisms, and Structure, 4th ed., 1992, pp. 437-438, hereby expressly incorporated herein by reference. When Y is

##STR00502## wherein R.sup.7 is as defined above, protected alcohols 42 can be prepared by first reacting protected halo-alcohols 40 with a trialkyl phosphite according to the procedure described in Kosolapoff, 1951, Org. React. 6:273 followed by reacting the derived phosphonic diester with ammonia according to the procedure described in Smith et al., 1957, J. Org. Chem. 22:265, incorporated herein by reference. When Y is

##STR00503## protected alcohols 42 can be prepared by reacting their sulphonic acid derivatives (i.e., 42, wherein Y is --SO.sub.3H) with ammonia as described in Sianesi et al., 1971, Chem. Ber. 104:1880 and Campagna et al., 1994, Farmaco, Ed. Sci. 49:653, both of which citations are incorporated herein by reference).

##STR00504##

As further illustrated in Scheme 11, protected alcohols 42 can be deprotected providing alcohols 42a. The deprotection method depends on the identity of the alcohol-protecting group, see e.g., the procedures listed in Greene, T. W., Protective Groups in Organic Synthesis, 3rd edition 17-237 (1999), particularly see pages 48-49, incorporated herein by reference. One of skill in the art will readily be able to choose the appropriate deprotection procedure. When the alcohol is protected as an ether function (e.g., methoxymethyl ether), the alcohol is preferably deprotected with aqueous or alcoholic acid. Suitable deprotection reagents include, but are not limited to, aqueous hydrochloric acid, p-toluenesulfonic acid in methanol, pyridinium-p-toluenesulfonate in ethanol, Amberlyst H-15 in methanol, boric acid in ethylene-glycol-monoethylether, acetic acid in a water-tetrahydrofuran mixture, aqueous hydrochloric acid is preferred. Examples of such procedures are described, respectively, in Bernady et al., 1979, J. Org. Chem. 44:1438; Miyashita et al., 1977, J. Org. Chem. 42:3772; Johnston et al., 1988, Synthesis 393; Bongini et al., 1979, Synthesis 618; and Hoyer et al., 1986, Synthesis 655; Gigg et al., 1967, J. Chem. Soc. C, 431; and Corey et al., 1978, J. Am. Chem. Soc. 100:1942, all of which are incorporated herein by reference.

Scheme 11 depicts the synthesis of protected lactone alcohols 46 and lactone. Compound 46 corresponds to compounds of the formula W.sup.(1)(2)-Zm-OPG and, wherein W.sup.(1)(2) is a lactone group selected from:

##STR00505## Protected lactone alcohols 46 can be prepared from compounds of the formula 46, 45, or 44 by using well-known condensation reactions and variations of the Michael reaction. Methods for the synthesis of lactones are disclosed in Multzer in Comprehensive Organic Functional Group Transformations, A. R. Katritzky, O. Meth-Cohn and C. W. Rees, Eds. Pergamon: Oxford, 1995, vol 5, pp. 161-173, incorporated herein by reference. Mono-protected diols 43, electrophilic protected alcohols 44, and aldehydes 45 are readily available ether commercially (e.g., Aldrich Chemical Co., Milwaukee, Wis.) or by well known synthetic procedures.

When W.sup.(1)(2) is a beta-lactone group of the formula:

##STR00506## protected lactone alcohols 46 can be prepared from aldehydes 45 and electrophilic protected alcohols 44, respectively, by a one-pot-addition-lactonization according to the procedure of Masamune et al., 1976, J. Am. Chem. Soc. 98:7874 and Danheiser et al., 1991, J. Org. Chem. 56:1176, both of which are incorporated herein by reference. This one-pot-addition-lactonization methodology has been reviewed by Multzer in Comprehensive Organic Functional Group Transformations, A. R. Katritzky, O. Meth-Cohn and C. W. Rees, Eds. Pergamon: Oxford, 1995, vol 5, pp. 161, incorporated herein by reference When W.sup.(1)(2) is a gamma- or delta-lactone group of the formula:

##STR00507## protected lactone alcohols 46 can be prepared from aldehydes 45 according to well known synthetic methodology. For example, the methodology described in Masuyama et al., 2000, J. Org. Chem. 65:494; Eisch et al., 1978, J. Organo. Met. Chem. C8 160; Eaton et al., 1947, J. Org. Chem. 37:1947; Yunker et al., 1978, Tetrahedron Lett. 4651; Bhanot et al., 1977, J. Org. Chem. 42:1623; Ehlinger et al., 1980, J. Am. Chem. Soc. 102:5004; and Raunio et al., 1957, J. Org. Chem. 22:570, all of which citations are incorporated herein by reference. For instance, as described in Masuyama et al., 2000, J. Org. Chem. 65:494, aldehydes 45 can be treated with about 1 equivalent of a strong organometallic base, preferably with a pK.sub.a of about 25 or more, more preferably with a pK.sub.a of greater than about 35, in a suitable organic solvent to give a reaction mixture. Suitable bases include, but are not limited to, alkylmetal bases such as methyllithium, n-butyllithium, tert-butyllithium, sec-butyllithium, phenyllithium, phenyl sodium, and phenyl potassium; metal amide bases such as lithium amide, sodium amide, potassium amide, lithium tetramethylpiperidide, lithium diisopropylamide, lithium diethylamide, lithium dicyclohexylamide, sodium hexamethyldisilazide, and lithium hexamethyldisilazide; and hydride bases such as sodium hydride and potassium hydride, preferably lithium tetramethylpiperidide. Suitable solvents include, but are not limited to, diethyl ether and tetrahydrofuran. The reaction-mixture temperature is adjusted to within the range of about 0.degree. C. to about 100.degree. C., preferably about room temperature to about 50.degree. C., and a halide of the formula:

##STR00508## wherein z is 1 or 2 (diluted with a solvent or in undiluted form) is added. The reaction mixture is stirred for a period of about 2 hours to about 48 hours, preferably about 5 to about 10 hours, during which time the reaction's progress can be followed by using an appropriate analytical technique, such as thin layer chromatography or high performance liquid chromatography. When the reaction is deemed substantially complete, protected lactone alcohols 46 can be isolated by workup and purified if desired. When W.sup.(1)(2) is a gamma- or delta-lactone group of the formula:

##STR00509## protected lactone alcohols 46 can be synthesized by deprotonating the corresponding lactone with a strong base providing the lactone enolate and reacting the enolate with electrophilic protected alcohols 44 (for a detailed discussion of enolate formation of active methylene compounds such as lactones, see House Modern Synthetic Reactions; W. A. Benjamin, Inc. Philippines 1972 pp. 492-570, and for a discussion of reaction of lactone enolates with electrophiles such as carbonyl compounds, see March, J. Advanced Organic Chemistry; Reactions Mechanisms, and Structure, 4th ed., 1992, pp. 944-945, both of which are incorporated herein by reference). Lactone-enolate formation can be accomplished by adding about 1 equivalent of a strong organometallic base, preferably with a pK.sub.a of about 25 or more, more preferably with a pK.sub.a of greater than about 35, to a mixture comprising a suitable organic solvent and the lactone. Suitable bases include, but are not limited to, alkylmetal bases such as methyllithium, n-butyllithium, tert-butyllithium, sec-butyllithium, phenyllithium, phenyl sodium, and phenyl potassium; metal amide bases such as lithium amide, sodium amide, potassium amide, lithium tetramethylpiperidide, lithium diisopropylamide, lithium diethylamide, lithium dicyclohexylamide, sodium hexamethyldisilazide, and lithium hexamethyldisilazide; and hydride bases such as sodium hydride and potassium hydride, preferably lithium tetramethylpiperidide. Solvents suitable for lactone-enolate formation include, but are not limited to, diethyl ether and tetrahydrofuran. After enolate formation, the reaction-mixture temperature is adjusted to within the range of about -78.degree. C. to about room temperature, preferably about -50.degree. C. to about 0.degree. C., and electrophilic protected alcohols 44 (diluted with a solvent or in undiluted form) are added, preferably at a rate such that the reaction-mixture temperature remains within about one to two degrees of the initial reaction-mixture temperature. The reaction mixture is stirred for a period of about 15 minutes to about 5 hours, during which time the reaction's progress can be followed by using an appropriate analytical technique, such as thin layer chromatography or high performance liquid chromatography. When the reaction is deemed substantially complete, protected lactone alcohols 46 can be isolated by workup and purified if desired. When W.sup.(1)(2) is a lactone group of the formula:

When W.sup.(1)(2) is a gamma- or delta-lactone group of the formula:

##STR00511## protected lactone alcohols 46 can be prepared according to a three step sequence. The first step comprises base-mediated reaction of electrophilic protected alcohols 44 with succinic acid esters (i.e., R.sup.9O.sub.2CCH.sub.2CH.sub.2CO.sub.2R.sup.9, wherein R.sup.9 is alkyl) or glutaric acid esters (i.e., R.sup.9O.sub.2CCH.sub.2CH.sub.2CH.sub.2CO.sub.2R.sup.9, wherein R.sup.9 is alkyl) providing a diester intermediate of the formula 44i:

##STR00512## wherein x is 1 or 2 depending on whether the gamma or delta lactone group is desired. The reaction can be performed by adding about 1 equivalent of a strong organometallic base, preferably with a pK.sub.a of about 25 or more, more preferably with a pK.sub.a of greater than about 35, to a mixture comprising a suitable organic solvent and the succinic or glutaric acid ester.

When the reaction is deemed substantially complete, the diester intermediate be isolated by workup and purified if desired. In the second step, the intermediate diester can be reduced, with a hydride reducing agent, to yield a diol:

##STR00513## The reduction can be performed according to the procedures referenced in March, J.

Suitable reducing agents include, but are not limited to, lithium aluminum hydride, diisobutylaluminum hydride, sodium borohydride, and lithium borohydride). In the third step, the diol can be oxidatively cyclized with RuH.sub.2(PPh.sub.3).sub.4 to the product protected lactone alcohols 46 according to the procedure of Yoshikawa et al., 1986, J. Org.

Scheme 13 depicts the synthesis of compounds ma, that is, compounds III where a double bond is not present in the ring. In the first step, compounds 53, prepared as discussed in Schemes 1 to 6 above, can be converted to compounds 54 by standard oxidation of the primary alcohol to an aldehyde group. Such oxidations are described in M. Hudlicky, Oxidations in Organic Chemistry, ACS Monograph 186, 1990, pp. 114-127, hereby expressly incorporated herein by reference. In the next step Grignard reaction of 54 with 55 followed by standard OH protection gives 57. Compounds 55 are commercially available (e.g., from Aldrich Chemical Co. Milwaukee, Wis.) or readily prepared by standard synthetic methodology. For exemplary procedures for Grignard reaction see March, J. Advanced Organic Chemistry; Reactions Mechanisms, and Structure, 4th ed., 1992, pp. 920-929, incorporated herein by reference. Similarly, in the next step, the Grignard salt of 57 is condensed with 58 to provide 59. Next 59 is oxidized and then cyclized to 60. When p is one, exemplary cyclization procedures are found in Friedrichsen, W. in Comprehensive Heterocyclic Chemistry II; Katritzky, A. R.; Rees, W. C.; Scriven, E. F. V. Eds.; Pergamon Press: Oxford, 1996; Vol. 2, p 351, and Comprehensive Heterocyclic Chemistry; Katritzky, A. R.; Rees, W. C. Eds.; Pergamon Press: Oxford, 1986; Vol. 3. When p is 0, cyclization procedures are found in Hepworth, J. D. in Comprehensive Heterocyclic Chemistry II; Katritzky, A. R; Rees, W. C.; Scriven, E. F. V.

W., Protective Groups in Organic Synthesis, 3rd edition (1999). For other structures, where Y is a group such as an acid, aldehydes, etc., protection is needed (acids as esters, preferably pivaloyl, aldehydes as silyl derivatives such as TIPS, stable in both basic and acidic conditions). When W.sup.(1)(2) is a Lactone it can be introduced as discussed in Scheme 3 above. The compounds are then coupled to afford compound of the formula IIIa.

The reactions are performed under similar conditions for substituted cyclic compounds. After the formation of the mono-cyclic compounds, they are in situ reacted with electrophiles (e.g., MeI) at temperatures between -40.degree. C. to +60.degree. C., for a reaction time of 1 hr to 5 days.

In a specific embodiment, the Compound of the Invention is administered concurrently with the chemotherapeutic agent or with radiation therapy. In another specific embodiment, the chemotherapeutic agent or radiation therapy is administered prior or subsequent to administration of a Compound of the Invention, preferably at least an hour, five hours, 12 hours, a day, a week, a month, more preferably several months (e.g., up to three months), prior or subsequent to administration of a Compound of the Invention.

A chemotherapeutic agent can be administered over a series of sessions, any one or a combination of the chemotherapeutic agents listed in Table 3 can be administered. With respect to radiation, any radiation therapy protocol can be used depending upon the type of cancer to be treated. For example, but not by way of limitation, x-ray radiation can be administered; in particular, high-energy megavoltage (radiation of greater that 1 MeV energy) can be used for deep tumors, and electron beam and orthovoltage x-ray radiation can be used for skin cancers. Gamma-ray emitting radioisotopes, such as radioactive isotopes of radium, cobalt and other elements, can also be administered. Additionally, the invention provides methods of treatment of cancer with a Compound of the Invention as an alternative to chemotherapy or radiation therapy where the chemotherapy or the radiation therapy has proven or can prove too toxic, e.g., results in unacceptable or unbearable side effects, for the subject being treated. The animal being treated can, optionally, be treated with another cancer treatment such as surgery, radiation therapy or chemotherapy, depending on which treatment is found to be acceptable or bearable.

The Compounds of the Invention can also be used in an in vitro or ex vivo fashion, such as for the treatment of certain cancers, including, but not limited to leukemias and lymphomas, such treatment involving autologous stem cell transplants. This can involve a multi-step process in which the animal's autologous hematopoietic stem cells are harvested and purged of all cancer cells, the patient's remaining bone-marrow cell population is then eradicated via the administration of a high dose of a Compound of the Invention with or without accompanying high dose radiation therapy, and the stem cell graft is infused back into the animal. Supportive care is then provided while bone marrow function is restored and the animal recovers.

4.15. Surgical Uses

Cardiovascular diseases such as atherosclerosis often require surgical procedures such as angioplasty. Angioplasty is often accompanied by the placement of a reinforcing a metallic tube shaped structure known as a "stent" into a damaged coronary artery. For more serious conditions, open heart surgery such as coronary bypass surgery may be required. These surgical procedures entail using invasive surgical devices and/or implants, and are associated with a high risk of restenosis and thrombosis. Accordingly, the compounds and compositions of the invention may be used as coatings on surgical devices (e.g., catheters) and implants (e.g., stents) to reduce the risk of restenosis and thrombosis associated with invasive procedures used in the treatment of cardiovascular diseases.

4.16. Veterinary and Livestock Uses

A composition of the invention can be administered to a non-human animal for a veterinary use for treating or preventing a disease or disorder disclosed herein.

In a specific embodiment, the non-human animal is a household pet. In another specific embodiment, the non-human animal is a livestock animal. In a preferred embodiment, the non-human animal is a mammal, most preferably a cow, horse, sheep, pig, cat, dog, mouse, rat, rabbit, or guinea pig. In another preferred embodiment, the non-human animal is a fowl species, most preferably a chicken, turkey, duck, goose, or quail.

In addition to veterinary uses, the compounds and compositions of the invention can be used to reduce the fat content of livestock to produce leaner meats. Alternatively, the compounds and compositions of the invention can be used to reduce the cholesterol content of eggs by administering the compounds to a chicken, quail, or duck hen. For non-human animal uses, the compounds and compositions of the invention can be administered via the animals' feed or orally as a drench composition.

The invention provides methods of treatment and prophylaxis by administration to a patient of a therapeutically effective amount of a compound or a composition comprising a compound of the invention. The patient is an animal, including, but not limited, to an animal such a cow, horse, sheep, pig, chicken, turkey, quail, cat, dog, mouse, rat, rabbit, guinea pig, etc., and is more preferably a mammal, and most preferably a human.

The compounds and compositions of the invention, are preferably administered orally. The compounds and compositions of the invention may also be administered by any other convenient route, for example, by intravenous infusion or bolus injection, by absorption through epithelial or mucocutaneous linings (e.g., oral mucosa, rectal and intestinal mucosa, etc.) and may be administered together with another biologically active agent. Administration can be systemic or local. Various delivery systems are known, e.g., encapsulation in liposomes, microparticles, microcapsules, capsules, etc., and can be used to administer a compound of the invention. In certain embodiments, more than one compound of the invention is administered to a patient. Methods of administration include but are not limited to intradermal, intramuscular, intraperitoneal, intravenous, subcutaneous, intranasal, epidural, oral, sublingual, intranasal, intracerebral, intravaginal, transdermal, rectally, by inhalation, or topically, particularly to the ears, nose, eyes, or skin. The preferred mode of administration is left to the discretion of the practitioner, and will depend in-part upon the site of the medical condition. In most instances, administration will result in the release of the compounds of the invention into the bloodstream.

In specific embodiments, it may be desirable to administer one or more compounds of the invention locally to the area in need of treatment. This may be achieved, for example, and not by way of limitation, by local infusion during surgery, topical application, e.g., in conjunction with a wound dressing after surgery, by injection, by means of a catheter, by means of a suppository, or by means of an implant, said implant being of a porous, non-porous, or gelatinous material, including membranes, such as sialastic membranes, or fibers. In one embodiment, administration can be by direct injection at the site (or former site) of an atherosclerotic plaque tissue.

In certain embodiments, for example, for the treatment of Alzheimer's Disease, it may be desirable to introduce one or more compounds of the invention into the central nervous system by any suitable route, including intraventricular, intrathecal and epidural injection. Intraventricular injection may be facilitated by an intraventricular catheter, for example, attached to a reservoir, such as an Ommaya reservoir.

Pulmonary administration can also be employed, e.g., by use of an inhaler or nebulizer, and formulation with an aerosolizing agent, or via perfusion in a fluorocarbon or synthetic pulmonary surfactant. In certain embodiments, the compounds of the invention can be formulated as a suppository, with traditional binders and vehicles such as triglycerides.

In another embodiment, the compounds and compositions of the invention can be delivered in a vesicle, in particular a liposome (see Langer, 1990, Science 249:1527 1533; Treat et al., in Liposomes in the Therapy of Infectious Disease and Cancer, Lopez-Berestein and Fidler (eds.), Liss, New York, pp. 353 365 (1989); Lopez Berestein, ibid., pp. 317 327; see generally ibid.).

In yet another embodiment, the compounds and compositions of the invention can be delivered in a controlled release system. In one embodiment, a pump may be used (see Langer, supra; Sefton, 1987, CRC Crit. Ref. Biomed. Eng. 14:201; Buchwald et al., 1980, Surgery 88:507 Saudek et al., 1989, N. Engl. J. Med. 321:574). In another embodiment, polymeric materials can be used (see Medical Applications of Controlled Release, Langer and Wise (eds.), CRC Pres., Boca Raton, Fla. (1974); Controlled Drug Bioavailability, Drug Product Design and Performance, Smolen and Ball (eds.), Wiley, New York (1984); Ranger and Peppas, 1983, J. Macromol. Sci. Rev. Macromol. Chem. 23:61; see also Levy et al., 1985, Science 228:190; During et al., 1989, Ann. Neurol. 25:351; Howard et al., 1989, J. Neurosurg. 71:105). In yet another embodiment, a controlled-release system can be placed in proximity of the target area to be treated, e.g., the liver, thus requiring only a fraction of the systemic dose (see, e.g., Goodson, in Medical Applications of Controlled Release, supra, vol. 2, pp. 115 138 (1984)). Other controlled-release systems discussed in the review by Langer, 1990, Science 249:1527 1533) may be used.

The present compositions will contain a therapeutically effective amount of a compound of the invention, optionally more than one compound of the invention, preferably in purified form, together with a suitable amount of a pharmaceutically acceptable vehicle so as to provide the form for proper administration to the patient.

In a specific embodiment, the term "pharmaceutically acceptable" means approved by a regulatory agency of the Federal or a state government or listed in the U.S. Pharmacopeia or other generally recognized pharmacopeia for use in animals, and more particularly in humans. The term "vehicle" refers to a diluent, adjuvant, excipient, or carrier with which a compound of the invention is administered. Such pharmaceutical vehicles can be liquids, such as water and oils, including those of petroleum, animal, vegetable or synthetic origin, such as peanut oil, soybean oil, mineral oil, sesame oil and the like. The pharmaceutical vehicles can be saline, gum acacia, gelatin, starch paste, talc, keratin, colloidal silica, urea, and the like. In addition, auxiliary, stabilizing, thickening, lubricating and coloring agents may be used. When administered to a patient, the compounds and compositions of the invention and pharmaceutically acceptable vehicles are preferably sterile. Water is a preferred vehicle when the compound of the invention is administered intravenously. Saline solutions and aqueous dextrose and glycerol solutions can also be employed as liquid vehicles, particularly for injectable solutions. Suitable pharmaceutical vehicles also include excipients such as starch, glucose, lactose, sucrose, gelatin, malt, rice, flour, chalk, silica gel, sodium stearate, glycerol monostearate, talc, sodium chloride, dried skim milk, glycerol, propylene, glycol, water, ethanol and the like. The present compositions, if desired, can also contain minor amounts of wetting or emulsifying agents, or pH buffering agents.

The present compositions can take the form of solutions, suspensions, emulsion, tablets, pills, pellets, capsules, capsules containing liquids, powders, sustained-release formulations, suppositories, emulsions, aerosols, sprays, suspensions, or any other form suitable for use. In one embodiment, the pharmaceutically acceptable vehicle is a capsule (see e.g., U.S. Pat. No. 5,698,155). Other examples of suitable pharmaceutical vehicles are described in "Remington's Pharmaceutical Sciences" by E. W. Martin.

In a preferred embodiment, the compounds and compositions of the invention are formulated in accordance with routine procedures as a pharmaceutical composition adapted for intravenous administration to human beings. Typically, compounds and compositions of the invention for intravenous administration are solutions in sterile isotonic aqueous buffer. Where necessary, the compositions may also include a solubilizing agent. Compositions for intravenous administration may optionally include a local anesthetic such as lignocaine to ease pain at the site of the injection. Generally, the ingredients are supplied either separately or mixed together in unit dosage form, for example, as a dry lyophilized powder or water free concentrate in a hermetically sealed container such as an ampoule or sachette indicating the quantity of active agent. Where the compound of the invention is to be administered by intravenous infusion, it can be dispensed, for example, with an infusion bottle containing sterile pharmaceutical grade water or saline. Where the compound of the invention is administered by injection, an ampoule of sterile water for injection or saline can be provided so that the ingredients may be mixed prior to administration.

Compounds and compositions of the invention for oral delivery may be in the form of tablets, lozenges, aqueous or oily suspensions, granules, powders, emulsions, capsules, syrups, or elixirs. Compounds and compositions of the invention for oral delivery can also be formulated in foods and food mixes. Orally administered compositions may contain one or more optionally agents, for example, sweetening agents such as fructose, aspartame or saccharin; flavoring agents such as peppermint, oil of wintergreen, or cherry, coloring agents; and preserving agents, to provide a pharmaceutically palatable preparation. Moreover, where in tablet or pill form, the compositions may be coated to delay disintegration and absorption in the gastrointestinal tract thereby providing a sustained action over an extended period of time. Selectively permeable membranes surrounding an osmotically active driving compound are also suitable for orally administered compounds and compositions of the invention. In these later platforms, fluid from the environment surrounding the capsule is imbibed by the driving compound, which swells to displace the agent or agent composition through an aperture. These delivery platforms can provide an essentially zero order delivery profile as opposed to the spiked profiles of immediate release formulations. A time delay material such as glycerol monostearate or glycerol stearate may also be used. Oral compositions can include standard vehicles such as mannitol, lactose, starch, magnesium stearate, sodium saccharine, cellulose, magnesium carbonate, etc. Such vehicles are preferably of pharmaceutical grade.

The amount of a compound of the invention that will be effective in the treatment of a particular disorder or condition disclosed herein will depend on the nature of the disorder or condition, and can be determined by standard clinical techniques. In addition, in vitro or in vivo assays may optionally be employed to help identify optimal dosage ranges. The precise dose to be employed in the compositions will also depend on the route of administration, and the seriousness of the disease or disorder, and should be decided according to the judgment of the practitioner and each patient's circumstances. However, suitable dosage ranges for oral administration are generally about 0.001 milligram to 2000 milligrams of a compound of the invention per kilogram body weight. In specific preferred embodiments of the invention, the oral dose is 0.01 milligram to 1000 milligrams per kilogram body weight, more preferably 0.1 milligram to 100 milligrams per kilogram body weight, more preferably 0.5 milligram to 25 milligrams per kilogram body weight, and yet more preferably 1 milligram to 10 milligrams per kilogram body weight. In a most preferred embodiment, the oral dose is 5 milligrams of a compound of the invention per kilogram body weight. The dosage amounts described herein refer to total amounts administered; that is, if more than one compound of the invention is administered, the preferred dosages correspond to the total amount of the compounds of the invention administered. Oral compositions preferably contain 10% to 95% active ingredient by weight.

Suitable dosage ranges for intravenous (i.v.) administration are 0.01 milligram to 1000 milligrams per kilogram body weight, 0.1 milligram to 350 milligrams per kilogram body weight, and 1 milligram to 100 milligrams per kilogram body weight. Suitable dosage ranges for intranasal administration are generally about 0.01 pg/kg body weight to 1 mg/kg body weight. Suppositories generally contain 0.01 milligram to 50 milligrams of a compound of the invention per kilogram body weight and comprise active ingredient in the range of 0.5% to 10% by weight. Recommended dosages for intradermal, intramuscular, intraperitoneal, subcutaneous, epidural, sublingual, intracerebral, intravaginal, transdermal administration or administration by inhalation are in the range of 0.001 milligram to 200 milligrams per kilogram of body weight. Suitable doses of the compounds of the invention for topical administration are in the range of 0.001 milligram to 1 milligram, depending on the area to which the compound is administered. Effective doses may be extrapolated from dose-response curves derived from in vitro or animal model test systems. Such animal models and systems are well known in the art.

The invention also provides pharmaceutical packs or kits comprising one or more containers filled with one or more compounds of the invention. Optionally associated with such container(s) can be a notice in the form prescribed by a governmental agency regulating the manufacture, use or sale of pharmaceuticals or biological products, which notice reflects approval by the agency of manufacture, use or sale for human administration. In a certain embodiment, the kit contains more than one compound of the invention. In another embodiment, the kit comprises a compound of the invention and another lipid-mediating compound, including but not limited to a statin, a thiazolidinedione, or a fibrate.

The compounds of the invention are preferably assayed in vitro and in vivo, for the desired therapeutic or prophylactic activity, prior to use in humans. For example, in vitro assays can be used to determine whether administration of a specific compound of the invention or a combination of compounds of the invention is preferred for lowering fatty acid synthesis. The compounds and compositions of the invention may also be demonstrated to be effective and safe using animal model systems.

Other methods will be known to the skilled artisan and are within the scope of the invention.

The following examples are provided by way of illustration and not limitation.

5. EXAMPLES

5.1. Keto-Substituted .alpha.-Cycloalkyldicarboxylic Acids

The cycloalkyl substituted keto-derivatives H are prepared as shown in Scheme 14 by methods already described in Dasseux, J.-L. H. et al. Ketone compounds and compositions for cholesterol management and related uses. U.S. patent application publication 20030078239, Oct. 11, 2001. The key step in the syntheses of most of the compounds of the invention is the alkylation of the formaldehyde synthon: Tosylmethyl Isocyanide (TosMIC) (Possel, O. et al. Tetrahedron Lett., 1977, 17, 4229-4232; Kurosawa, K. et al. Tetrahedron Lett., 1982, 23, 5335-5338; Yadav, J. S. et al. Tetrahedron Lett., 1990, 31, 6217-6218; van Leusen, D. et al. Synthetic Uses of Tosylmethyl Isocyanide (TosMIC). In Organic Reactions, Vol. 57; Overman, L. E., Editor-in-Chief; John Wiley and Sons, Inc.: New York, 2001; pp 417-666) with a properly functionalized halo-ester, which is available commercially (e.g., Aldrich Chemical Co., Milwaukee, Wis.) or can be prepared by well-known methods such as halogenation or sulfonation of butanediol.

##STR00517##

In a typical procedure, a halo-ester is prepared via alkylation of commercially available or known esters of type 101 with a dihaloalkane of type 102 of proper length as described in Scheme 15. Cycloakyl carboxylic esters of type 101 prepared for this invention are used for the preparation of haloesters described in Table 1. Ethyl, butyl and t-butyl ester analogues of 101 could be used as starting material. As an example, ethyl cyclopropylcarboxylate, which is known to self-condensate on treatment with various bases, as described in Pinnick, H. W. et al. J. Org. Chem., 1980, 45, 4505-4507, cannot be used for this reaction, and the corresponding t-butyl analogue is used instead, which is prepared as described in the literature (Haener, R. et al. Helv. Chim. Acta, 1986, 69, 1655-1665). In a typical procedure, bromo-esters 103a-g are prepared via treatment of 101 with LDA and a large excess of a dibromoalkane (102, X.dbd.Br) or bromo-chloroalkane (102, X.dbd.Cl) in THF at low temperatures. The crude product 104 is separated from excess of 102 via fractional distillation. If iododerivatives are needed due to the lack of reactivity of the chloro-ester derivatives (104a-c), the latter are converted to the corresponding iodides (105a-c) by methods known in the literature prior to their reaction with TosMIC. In the case of the bromo-esters (103a-g) treatment with a catalytic amount of Bu.sub.4NI suffices to form the corresponding iodo compounds in situ.

Symmetrical ketones are prepared by Method A (e.g. TosMIC, NaH, 3, Bu.sub.4NI in DMSO) as described in Scheme 16. The intermediate dialkylated TosMIC derivatives is treated with cone HCl in CH.sub.2Cl.sub.2 to provide keto-diesters 106d, g-h, j, m-n in moderate to good yield as shown in Scheme 15 and Table 2. For the preparation of keto-diacids 106c, e-f, k-l Method B is applied (e.g., KOtBu, 105 in N,N-dimethylacetamide at temperatures between -10.degree. C. to 35.degree. C., preferably room temperature), which is similar to the one described by Haener, R. et al. Helv. Chim. Acta, 1986, 69, 1655-1665 and products are obtained as described in Table 2.

##STR00519##

For the preparation of asymmetrical ketones 106c, e, k a set of mono-alkylated TosMIC derivatives (108a,b) are used as starting materials that are prepared as described in Scheme 17. As such intermediates could only be produced in low yield via Method A the more selective conditions (K.sub.2CO.sub.3, DMAc) are applied, providing 108a,b in good yield (Table 3). Subsequent treatment of 108a,b as reported for Method A or B afforded the asymmetrical ketones 106c, e, k (Table 2). The target keto-diacids (107) were prepared from the corresponding ester analogues (106) by saponification of the linear alkane esters (Et, Bu), treatment of the t-butyl esters with HCO.sub.2H or a combination of the two (Schemes 3 and 4). Preparations are similar for compounds with other terminal groups than acids, as described in Dasseux, J.-L. H. et al. Ketone compounds and compositions for cholesterol management and related uses.

Long hydrocarbon chain keto-diols and -acids was synthesized as described in Schemes 18 and 19, and Table 4 (Dasseux, J.-L. H. et al. Ketone compounds and compositions for cholesterol management and related uses. U.S. patent application 20030078239, Oct. 11, 2001). The side chains connected to the central ketone functionality varied both in length (m, m=3-7) and in the attached geminal modifying groups (R.sup.1, R.sup.2=Me, Ph, 4-Me-C.sub.6H.sub.4, 4-iBu-C.sub.6H.sub.4). The majority of target compounds fell in the category of either symmetrical ketodiacids (210b-210g, 210i, 210j, Scheme 18) or symmetrical ketodiols (214a-214i, Scheme 19).

The key step in the syntheses of all ketones with aliphatic chains was the alkylation of tosylmethyl isocyanide (TosMIC) (Possel, O. et al.

E., Editor-in-Chief; John Wiley and Sons, Inc.: New York, 2001; pp 417-666) with appropriately substituted alkyl bromides (Schemes 18-22). These alkyl bromide building blocks were generally synthesized via lithiation of commercially available or readily accessible ethyl esters 201, 202 (Shiner, V. J., Jr. et al. The Arrhenius Parameters of the Deuterium Isotope Rate Effect in a Base-promoted Elimination Reaction: Evidence for Proton Tunneling. J. Am. Chem. Soc. 1961, 83, 593-598), 203 (Ghosh, S. et al.

Chem. 1987, 30, 1812-1818) of the required chain length (Scheme 18). Thus, bromo esters 205a-205j were obtained in moderate to good yields (Table 4). Reduction of bromo esters with lithium borohydride and methanol (Brown, H. C. et al. 30. Effect of Cation and Solvent on the Reactivity of Saline Borohydrides for Reduction of Carboxylic Esters. Improved Procedures for the Conversion of Esters to Alcohols by Metal Borohydrides. J. Org. Chem. 1982, 47, 4702-4708; Soai, K. et al. Mixed Solvents Containing Methanol as Useful Reaction Media for Unique Chemoselective Reductions with Lithium Borohydride. J. Org. Chem. 1986, 51, 4000-4005) in refluxing dichloromethane afforded the bromo alcohols 206a-206e, 206g, and 206h in excellent yields and purities without effecting the bromide moiety. The chemoselectivity of reduction of similar bromo esters with LiAlH.sub.4 depended on the conditions. In ether at room temperature the bromo alcohol was the single product whereas in THF at reflux the reaction gave the alcohols exclusively. See: Beckwith, A. L. J. et al. Stereochemistry of the Reversible Cyclization of .omega.-Formyl Radicals. J. Org. Chem. 1992, 57, 4954-4962. Reduction with lithium aluminum hydride or sodium borohydride on the other hand was not chemoselective and the reactions were not reproducible. Another chemoselective reducing agent was diisobutylaluminum hydride (Brown, H. C. et al. Selective Reductions. 30. Effect of Cation and Solvent on the Reactivity of Saline Borohydrides for Reduction of Carboxylic Esters. Improved Procedures for the Conversion of Esters to Alcohols by Metal Borohydrides. J. Org. Chem. 1982, 47, 4702-4708). Bromo alcohols were treated with 3,4-dihydro-2H-pyran and catalytic amounts of p-toluenesulfonic acid (Brown, H. C. et al. Selective Reductions. 30. Effect of Cation and Solvent on the Reactivity of Saline Borohydrides for Reduction of Carboxylic Esters. Improved Procedures for the Conversion of Esters to Alcohols by Metal Borohydrides. J. Org. Chem. 1982, 47, 4702-4708) to give the THP ethers 207a-207e, 207g, and 207h (Scheme 18, Table 4) in moderate to good yields.

The synthesis of symmetrical ketodiacids 210b-210g, 210i, and 210j from bromo esters 205b-205g, 205i, and 205j was accomplished employing TosMIC methodology as described above (Scheme 2). Accordingly, TosMIC was deprotonated with sodium hydride in either DMSO or in a DMSO/diethyl ether mixture (Possel, O. et al. Tosylmethyl Isocyanide Employed in a Novel Synthesis of Ketones. A New Masked Formaldehyde Reagent. Tetrahedron Lett. 1977, 17, 4229-4232) at room temperature and then reacted with suitable bromo esters 205b-205g, 205i, and 205j in the presence of catalytic amounts of tetrabutylammonium iodide to give the corresponding dialkylated TosMIC intermediates 208a-208g, 208i, and 208j. These alkylations of TosMIC proceeded also without catalytic amounts of NBu.sub.4I, but required a slightly longer reaction time. In most cases, these intermediates were not purified or characterized but directly treated with coned aqueous HCl in dichloromethane (Prato, M. et al. Cleavage of the 1,3-Dithiane Protective Group. Synthesis 1982, 679-680) to give ketodiesters 209b-209g, 209i, and 209j in good yields after chromatographic purification (Table 2). Finally, hydrolysis of the ester groups with potassium hydroxide in aqueous ethanol and subsequent acidification with coned HCl (steps c, d) provided the target diacids 210b-210g, and 210j in variable yields ranging from 31 to 87%. According to a different protocol, ketodiacid 210i was prepared by simultaneous hydrolysis of the tosyl isocyanide and the ester groups in 281 with potassium hydroxide in aqueous ethanol followed by acidification with dilute sulfuric acid (steps c, e) in 57% yield.

Scheme 3 illustrates three different strategies that were studied for the synthesis of symmetrical ketodiols. The standard procedure used in most cases employed the dialkylation protocol of TosMIC as described above. Bromo THP ethers 207a-7e, 7g, and 7h were used as electrophiles and the resulting TosMIC intermediates were directly hydrolyzed to give the ketodiols 214a-214e, 214g, and 214h in acceptable yields after purification by column chromatography (Table 3). An alternative pathway was elected for the synthesis of ketodiol 214i. In this case, ketodiester 209i was first reduced to triol 211i by treatment with lithium aluminum hydride (66%). Selective oxidation of the secondary alcohol moiety in 211i with aqueous sodium hypochlorite solution in acetic acid (Stevens, R. V. et al. Further Studies on the Utility of Sodium Hypochlorite in Organic Synthesis. Selective Oxidation of Diols and Direct Conversion of Aldehydes to Esters. Tetrahedron Lett. 1982, 23, 4647-4650; Stevens, R. V. et al. Convenient and Inexpensive Procedure for Oxidation of Secondary Alcohols to Ketones. J. Org. Chem. 1980, 45, 2030-2032) then produced 214i in low yield (35%). Better results were obtained when the ketone functionality in a ketodiester was protected prior to the reduction of the esters. Thus, protection of 209f with 1,3-propanedithiol and boron trifluoride diethyl etherate (Hatch, R. P. et al. Studies on Total Synthesis of the Olivomycins. J. Org. Chem. 1978, 43, 4172-4177) led to formation of 212f, which was subsequently reduced with lithium aluminum hydride to 213f. Removal of the 1,3-dithiane protective group with DMSO in dimethoxyethane and coned HCl (Prato, M. et al. Cleavage of the 1,3-Dithiane Protective Group. Synthesis 1982, 679-680) afforded ketodiol 214f (63% from 205f). Despite the superior yields attained, this method was not generally applied for the synthesis of 214a-214i because of the malodorous reagent involved.

The unsymmetrical ketodiols 217-219 were prepared via the mono-alkylated TosMIC derivative 215 as a common intermediate (Scheme 21). However, reaction of TosMIC with one equivalent of 207c under the previously utilized reaction conditions (NaH and NBu.sub.4I in DMSO) gave a mixture of mono- and dialkylated products 215 and 216 (For similar successive alkylations of TosMIC with alkyl halides of different chain lengths, see: Rao, A. V. R. et al. A New Route for the Synthesis of 1,4-Dicarbonyl Compounds: Synthesis of Jasmone, Dihydrojasmone and a Prostaglandin Intermediate. Synth. Commun. 1984, 14, 469-475). Contaminant 216 had to be removed by chromatography to prevent formation of mixtures of 217 or 219, respectively, with 214e in the next step, which were practically impossible to separate; the yield of this purification was very low (27%). Modification of the conditions (K.sub.2CO.sub.3 in DMF) circumvented this problem as 215 was produced in 69% yield without formation of 216, even when an excess of 7c was used. Further alkylation of 215 with the respective bromo THP-ethers 207a, 207d, and 207g, followed by deprotection with coned HCl in refluxing methanol furnished the unsymmetrical products 217-219 in respectable yields.

Similar problems with an unwanted dialkylated by-product (208c, Scheme 19) were also encountered in the synthetic route to diacids 225 and 226. Alkylation of TosMIC with 205e by treatment with NaH and NBu.sub.4I in DMSO led to a mixture of compounds 220 and 208c that was very difficult to separate by chromatographic means (For similar mono-alkylations of TosMIC with long chain bromo esters, see: Johnson, D. W. A Synthesis of Unsaturated Very Long Chain Fatty Acids. Chem. Phys. Lipids 1990, 56, 65-71). As a result, the yield of pure 220 was only 12%. To ensure the complete removal of the symmetrical ketodiester 209e that results from intermediate 208c, compound 220 was reacted with the bromo THP-ether 207a and subsequently hydrolyzed to give hydroxy ester 221. Purification of 221 from traces of 209c was now easily accomplished by chromatography (60% yield). Subsequent oxidation of this alcohol with pyridinium dichromate (PDC) in DMF (Vedejs, E. et al. J. Am. Chem. Soc. 1987, 109, 5437-5446) afforded diacid monoester 223 (79%), which was further saponified to provide 225 in 60% yield after crystallization from diethyl ether/hexanes.

The same strategy was applied for the synthesis of the unsymmetrical ketodiacid 226. In this case, intermediate 220 was not isolated, but further alkylated in situ with bromo THP-ether 207g. After deprotecting the ketone group by acid treatment and purification of the crude product by chromatography, hydroxy ester 222 was isolated in 36% yield. In analogy to its shorter chain homologue 221, oxidation of compound 222 with PDC in DMF led to ketodiacid mono-ester 224 (68%). Subsequent hydrolysis of 224 with potassium hydroxide in aqueous ethanol followed by chromatographic purification and crystallization furnished 226 in 43% yield.

Benzophenone derivative 227, prepared similarly to the method described in Shultz, D. A. et al. The Effect of Phenyl Rin Torsional Rigidity on the Photophysical Behavior of Tetraphenylethylenes. J. Am. Chem. Soc. 1989, 111, 6311-6320, was used as starting material for the synthesis of aryl-bridged ketones 231 and 232. Bromide displacement in 227 by reaction with lithio ethyl isobutyrate in THF/DMPU at -78.degree. C. produced the diester 228 in 89% yield. Conversion of 228 to diacid 231 performed by saponification with KOH resulted in practically quantitative yield. For the synthesis of the related diol 232, the ketone moiety in intermediate 228 was first protected as S,S-acetal 229 (87%) as described in Rao, A. V. R. et al. A New Route for the Synthesis of 1,4-Dicarbonyl Compounds: Synthesis of Jasmone, Dihydrojasmone and a Prostaglandin Intermediate. Synth. Commun. 1984, 14, 469-475. Reduction with lithium borohydride and methanol gave diol 230 in 85% yield. Finally, deprotection with copper(II) oxide and copper(II) chloride in a refluxing acetone/DMF solvent mixture as described in Stutz, P. et al. 3-Alkylated and 3-Acylated Indoles from a Common Precursor: 3-Benzylindole and 3-Benzoylindole. In Organic Syntheses Collective Volume VI; Noland, W. E., Editor-in-Chief; John Wiley and Sons, Inc.: New York, 1988; pp 109-114 afforded ketodiol 232 in 71% yield.

6. BIOLOGICAL ASSAYS

6.1. Effects of Illustrative Compounds of the Invention on the In Vitro Lipid Synthesis in Isolated Hepatocytes

Compounds were tested for inhibition of lipid synthesis in primary cultures of rat hepatocytes. Male Sprague-Dawley rats were anesthetized with intraperitoneal injection of sodium pentobarbital (80 mg/kg). Rat hepatocytes were isolated essentially as described by the method of Seglen (Seglen, P. O. Hepatocyte suspensions and cultures as tools in experimental carcinogenesis. J. Toxicol. Environ. Health 1979, 5, 551-560). Hepatocytes were suspended in Dulbecco's Modified Eagles Medium containing 25 mM D-glucose, 14 mM HEPES, 5 mM L-glutamine, 5 mM leucine, 5 mM alanine, 10 mM lactate, 1 mM pyruvate, 0.2% bovine serum albumin, 17.4 mM non-essential amino acids, 20% fetal bovine serum, 100 nM insulin and 20 .mu.g/mL gentamycin) and plated at a density of 1.5.times.10.sup.5 cells/cm.sup.2 on collagen-coated 96-well plates. Four hours after plating, media was replaced with the same media without serum. Cells were grown overnight to allow formation of monolayer cultures. Lipid synthesis incubation conditions were initially assessed to ensure the linearity of [1-.sup.14C]-acetate incorporation into hepatocyte lipids for up to 4 hours. Hepatocyte lipid synthesis inhibitory activity was assessed during incubations in the presence of 0.25 .mu.Ci [1-.sup.14C]-acetate/well (final radiospecific activity in assay is 1 Ci/mol) and 0, 1, 3, 10, 30, 100 or 300 .mu.M of compounds for 4 hours. At the end of the 4-hour incubation period, medium was discarded and cells were washed twice with ice-cold phosphate buffered saline and stored frozen prior to analysis. To determine total lipid synthesis, 170 .mu.l of MicroScint-E.RTM. and 50 .mu.l water was added to each well to extract and partition the lipid soluble products to the upper organic phase containing the scintillant. Lipid radioactivity was assessed by scintillation spectroscopy in a Packard TopCount NXT. Lipid synthesis rates were used to determine the IC.sub.50s of the compounds that are presented in Table 6 and 7.

6.2. Effects of Illustrative Compounds of the Invention on NonHDL Cholesterol, HDL Cholesterol, Triglyceride Levels, Glycemic Control Indicators and Body Weight Control in Obese Female Zucker Rats

Ten- to twelve-week old (400-500 grams) female Zucker fatty rats Crl: (Zuc)-faBR were obtained from Charles River Laboratories. Animals were acclimated to the laboratory environment for seven days. During the acclimation and study period, animals were housed by group in shoebox polycarbonate cages on Cellu-Dri bedding. The temperature and humidity in the animals' quarters (68-78.degree. F.; 30-75% RH) were monitored and the airflow in the room was sufficient to provide several exchanges per hour with 100% fresh filtered air. An automatic timing device provided an alternating 12-hour cycle of light and dark. Rats received pelleted Purina Laboratory Rodent Chow.RTM. (5001) prior to and during the drug intervention period except for a 6-hour phase prior to blood sampling. Fresh water was supplied ad libitum via an automatic watering system. Compounds were dissolved, suspended by mixing in a dosing vehicle consisting of 1.5% carboxymethylcellulose/0.2% Tween 20 or 20% ethanol and 80% polyethylene glycol-200 [v/v]. Dose volume of vehicle or vehicle plus each compound was set at 0.25% of body weight in order to deliver the appropriate dose. Doses were administered daily by oral gavage, approximately between 8-10 AM. Regarding blood sampling, animals were fasted for 6 hours prior to all blood collections. Prior to and after 7 days of dosing, a 1.0- to 2.0-mL sample of blood was collected by administering O.sub.2/CO.sub.2 anesthesia and bleeding from the orbital venous plexus. Following 14 days of dosing, blood was collected by cardiac puncture after euthanasia with CO.sub.2. All blood samples were processed for separation of serum and stored at -80.degree. C. until analysis. Commercially available kits were used to determine serum triglycerides (Roche Diagnostic Corporation, Kit No. 148899 or Boehringer Mannheim, Kit No. 1488872), total cholesterol (Roche Diagnostic Corporation, Kit No. 450061), non-esterified fatty acids (Wako Chemicals, Kit No. 994-75409) and .beta.-hydroxybutyrate (Wako Chemicals, Kit No. 417-73501 or Sigma Kit. No. 310-0) on a Hitachi 912 Automatic Analyzer (Roche Diagnostic Corporation). In some instances, an in-house cholesterol reagent was used to determine total serum cholesterol levels. Serum lipoprotein cholesterol levels were determined by lipoprotein profile analysis. Lipoprotein profiles were analyzed using gel-filtration chromatography on a Superose 6HR (1.times.30 cm) column equipped with on-line detection of total cholesterol as described by Kieft et al (Kieft, K. A.; Bocan, T. M.; Krause, B. R. Rapid on-line determination of cholesterol distribution among plasma lipoproteins after high-performance gel filtration chromatography. J. Lipid Res. 1991, 32, 859-866.). The total cholesterol content of each lipoprotein was calculated by multiplying the independent values determined for serum total cholesterol by the percent area of each lipoprotein in the profile. The percent body weight gain and the ratio of liver to body weight is also determined. Selected data are shown as absolute values or as a percent change of the pretreatment values in Tables 8 and 9.
