| Abstract
| - The preparation of new and easily accessible chiral N-alkyloxaziridines for asymmetric sulfidesoxidation was investigated. Most significantly, we report here that inert N-alkyloxaziridines canbe activated by Lewis acids to achieve a fast, selective, and efficient oxygen atom transfer to sulfides.Asymmetric sulfoxidation by three new chiral oxaziridines (two of them were structurallycharacterized by X-ray analysis) afforded enantioselectivities ranging from 22% to 63% ee withthe simplest aryl alkyl sulfides.
