OBJECTIVE
To analyse the phenolics content of the most potent carbonic anhydrase-inhibiting fraction
From the dichloromethane extract of the roots of Peucedanum paniculatum L., two new coumarins, a species endemic to Corsica, have been isolated. Their structures were elucidated, on the basis of spectroscopic studies, particularly 1D and 2D NMR spectroscopy, as
Eight coumarins, which carry a terminal alkene tethered by a CH(2)XCH(2) group to their 4-position (X = CH(2), CMe(2), O, S, NBoc, NZ, NTs, NBn), were synthesized in overall yields of 51-80 %. Starting materials for the syntheses were either commercially available 4-hydroxycoumarin or
