The electronic effects of sulfur in γ-sulfenyl enones are not transmitted to the carbonyl carbon through the π bond as reported previously. The diastereoselectivity is rather controlled by a combination of several other factors. The steric effects arising from the substituents on the sulfur atom and the γ-carbon and the bulk of the nucleophile constitute the major control elements.
