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.
