| Abstract: | The preparation of optically active sulfilimines via the catalytic diastereoselective imination of sulfides using a chiral nitrene is described. Excellent yields up to 97% and good diastereoselectivities up to 96% have been obtained. Oxidation of the sulfilimines then stereospecifically affords the corresponding sulfoximines with very good yields in the 88-96% range. |
