Stereoselective Reaction of α-Sulfinyl Carbanion Derived from Chiral 2-(Trialkylsilyl)ethyl Sulfoxides: Evidence for a Novel Silicon−Oxygen Interaction
Reactions of alpha-sulfinyl carbanions, derivedfrom p-tolyl sulfoxides bearing various alkyl groups, with various electrophiles were examined. The reaction of alpha-sulfinyl carbanions, derivedfrom the beta-silylethyl sulfoxides, with ketones or trimethyl phosphate, gave the syn products with high stereoselectivity. Interaction between the silicon in the trialkylsilyl group and the carbonyl oxygen
