Mass-directed isolation of the CH(2)Cl(2)/MeOH extract of Doryphora sassafras resulted in the purification of a new benzylisoquinoline alkaloid, 1-(4-hydroxybenzyl)-6,7-methylenedioxy-2-methylisoquinolinium trifluoroacetate (1), and the known aporphine alkaloid (S)-isocorydine (2). The structures of
Chemical investigation of the Australian rainforest plant Doryphora sassafras has resulted in the isolation of a new natural product, 2-methyl-1-(p-methoxybenzyl)-6,7-methylenedioxyisoquinolinium chloride (1). The iodide salt of compound 1 has previously been synthesized but only partially
