DIBAL reduction of enantiomerically pure α-sulfinyl ketimines can be achieved almost completely stereoselectively under ZnX2 catalysis, regardless of the alkyl or aryl substituent at nitrogen and the aliphatic (cyclic or acyclic) or aromatic character of the imine. Steric factors as well as the electrophilic character of the hydride are responsible for the stereochemical course of the reduction.
