Stereoselective Synthesis via Claisen Rearrangements of the Marine Sterols Occelasterol, Patinosterol, and 22,23-Dihydrooccelasterol

Occelasterol (1a), patinosterol (2a), 22,23-dihydrooccelasterol (3a), and their 24-stereoisomers (1b, 2b, and 3b) were stereoselectively synthesized.The i-methyl ether 6, derived from stigmasterol, was coupled with propynylmagnesium bromide to afford an e
