Recent development in asymmetric catalytic oxidation of prochiral sulfides by metal-based catalysts

The most efficient way to generate chiral sulfoxides is asymmetric oxidation of prochiral sulfides catalyzed by chiral metal complexes. Recently, the rational design of chiral metal complexes for enantiomerically catalytic oxidation of sulfides attracts much attention. Applications of a variety of metal-based catalysts to asymmetric oxidation of sulfides were reviewed.
