The Potential Of Vanadium Bromoperoxidase As A Catalyst In Preparative Asymmetric Sulfoxidation

Vanadium bromoperoxidase (VBrPO) from Corallina officinalis was demonstrated to be a potentially useful catalyst for the preparation of (S)-sulfoxides of high enantiomeric purity. No loss in enantioselectivity or yield was observed upon a thirtyfoid increase of the reaction scale in the oxidation of 2-methylsulfanyl-benzoic acid (2). The catalytic activity of VBrPO in asymmetric sulfoxidation was demonstrated to be dependent on the vanadium content in the active site. The enzyme was found to be unable to catalyze asymmetric oxidation of alkenes and to bring about kinetic resolution of chiral hydroperoxides.
