resolution of racemic sulfoxides requires either custom substrates or shows moderate enantioselectivity, leading to achiral coproducts (such as sulfones) as an intrinsic part of the process. A new strategy is demonstrated that allows the resolution of racemic sulfoxides through catalytic asymmetric nitrene‐transfer reactions. This approach gives rise to both optically active sulfoxides and highly enantioenriched

The reaction of PhI=NTs with sulfoxides in the presence of catalytic amounts of CuOTf afforded the corresponding N-tosylsulfoximines in high yield. The use of enantiomerically pure sulfoxides allowed stereoselective access to N-tosylsulfoximines with complete retention of configuration at sulfur. (C) 1998 Elsevier Science Ltd.
