Abstract

Enantiopure aryl benzyl sulfoxides can be prepared ­using vanadium-Schiff base catalyzed sulfide oxidation and kinetic resolution of the resulting sulfoxide. The kinetic resolution can be effected in combination with asymmetric sulfide oxidation or instead starting from the racemic sulfoxide.
