The reaction of the (α-carbanion derived from (trimethylsilyl)vinyl sulfoxides with aldehydes afforded a diastereomeric mixture of the products. Each diastereomer was subjected to specific elimination reactions to give optically pure propargylic, trimethylsilylated propargylic, and allylic alcohols. Acceleration of the sulfenic acid-elimination from the β-silylvinyl sulfoxide was demonstrated by the ab initio calculation to be ascribed mainly to the β-effect of the silyl group.
Stereocontrolled asymmetric synthesis of optically active acylcyclopropane derivatives by Michael additions of bromomalonate to chiral α-acylvinylic sulfoxides

Michael addition of bromomalonate carbanions to chiral α-acylvinylic sulfoxides and the subsequent intramolecular alkylation yielded optically active acylcyclopropane derivatives with high enantiomeric excess. Stereochemistry of the product was determined by chemical correlation to a compound of known absolute configuration. The mechanism for the asymmetric induction is deduced on the basis of the stereochemical results obtained.
Fluoride-catalyzed generation and reactions of 1-(p-tolylsulfinyl)vinyl anion

Fluoride-catalyzed desilylation of p-tolyl 1-(trimethylsilyl) vinyl sulfoxide in the presence of aldehydes results in modest yields of the corresponding allylic alcohols. Upon treatment with alkaline solution at 0°C it undergoes efficient protodesilylatio
