APPLICATION OF SELENOSULFONATION TO MARINE STEROL SYNTHESIS. PREPARATION OF 24,28-DEHYDROAPLYSTEROL, XESTOSTEROL AND OSTREASTEROL FROM A COMMON ACETYLENIC INTERMADIATE

The title compounds were synthesized from a readily available steroidal acetylene by a protocol employing selenosulfonation, introduction of the appropriate side chain at C-24 via an alkyl selenocuprate, and reductive desulfonylation.
