Efficient amination of sulfides with a ketomalonate-derived oxaziridine: application to [2,3]-sigmatropic rearrangements of allylic sulfimides

A novel N-Boc-oxaziridine is reported, derived from diethyl ketomalonate, which effects efficient amination of sulfides to sulfimides. The reagent is applied to the [2,3]-sigmatropic rearrangement of allylic sulfimides.
