β-Asymmetric induction in the reduction of n-alkylidenesulphinamides. Synthesis of optically active amines

Abstract

Asymmetric synthesis occurs in the reduction by LiAlH₄ of optically active N-alkylidenesulphinamides; the sulphinamides thus obtained can be oxidized to optically active sulphonamides or cleaved to optically active amines of high optical purity.
