HIGHLY ENANTIOSELECTIVE ALDOL-TYPE REACTION OF 3-ACETYLTHIAZOLIDINE-2-THIONE WITH ACHIRAL ALDEHYDES

Abstract
A highly enantioselective aldol-type reaction forming various β-hydroxy carbonyl compounds from 3-acetylthiazolidine-2-thione and achiral aldehydes is achieved via divalent tin enolate employing chiral diamine derived from (S)-proline as a ligand.
