Abstract The 5α- and 5β-oriented Δ 3 -double bond isomers 8, 9 of the widely used progestin desogestrel (7) were synthesized. Wittig olefination reaction of the 5α-intermediate 12 showed a dramatically reduced reaction rate compared with the olefination of the 5β-intermediate 13 . Computational studies suggest that different energies of the intermediary 1,2-oxaphosphetanes may, at least partially, have been the reason for this phenomenon.
