2-(alkylthio)thiolane 1-oxides 2 were prepared in a three-step synthesis. The carbanions of 2 were generated with different bases and treated with iodomethane and carbonyl compounds to form the methyl derivatives 6 and the carbinols 7, respectively. The conformational stability (α-diastereoselectivity) of the carbanions as well as the asymmetric induction during the reaction with prochiral electrophiles
