Abstract

The nitrene transfer from t-butyloxycarbonyl azide (BocN₃) to several nucleophiles is promoted by ferrous chloride (FeCl₂) and yields the corresponding N-Boc protected sulfoximides, sulfimides, or α-amino alkanoates. Whereas the sulfoximide formation occurs spontaneously in CH₂Cl₂ as solvent the FeCl₂-catalyzed nitrene transfer to sulfides and ketene acetals requires addition of a polar solvent. DMF was found to be best suited for this purpose.
