Chemoenzymatic Deracemization of Chiral Sulfoxides

Abstract

Abstract The highly enantioselective enzyme methionine sulfoxide reductase A was combined with an oxaziridine‐type oxidant in a biphasic setup for the deracemization of chiral sulfoxides. Remarkably, high ee values were observed with a wide range of substrates, thus providing a practical route for the synthesis of enantiomerically pure sulfoxides.
