Abstract

We report that the new compound N-methoxycarbonyl-3- phenyloxaziridine 1 is an exceptionally mild and efficient reagent for the conversion of most primary and secondary amines :NH to the corresponding carbazates :N- NHC02Me. We could prepare oxaziridine 1 in multigram quantities by controlled oxidation+ of the N-methoxycarbonyl imino deriva- ... $ Oxaziridine 1: IH NMR (CDCl3, 27 "C, slow cisltrans equilibrium): the trans structure was assigned to the major ...
