Optically active 2-pyridylmethyl p-tolyl (1) and 2-(N-methylimidazolyl)methyl p-tolyl sulfoxides (2) were synthesized and the reactions of their chiral α-sulfinyl carbanions with aldehydes afforded stereoselectively the condensation products. The absolute configurations of the products were determined by X-ray crystallographic analysis and chemical reactions. The mechanism for the reactions is described.
