✦ Synopsis

The isolation and structure elucidation of marine sterols such as aplysterol (A),2 stelliferasterol (2)3 and strongylosterol (3)' represent the first evidence that bioalkylation5 of -the cholesterol side chain can occur at the terminus (C-27) as well as at the central positions 24 (and thence C-28), 23, and 22. By incorporating a plausible set of biosynthetic assumptions

A synthesis of (23R)-and (23S)-23H-calysterols 2a and 2b from pregnanoic ester 10 is reported. Alkylation of 10 with dibromide 19b, followed by reduction of the carboethyloxy group to a methyl group, afforded (Z)-vinylic bromide 22. Dibromocyclopropanation of 22 yielded the diastereomeric tri-
