Abstract

N-Bromo,N-lithio salts of primary carboxamides are efficient nitrogen sources for catalytic asymmetric aminohydroxylation of olefins, behaving much like the parent N-bromoacetamide in these reactions. α-Chloro-N-bromoacetamide is a particularly interesting nitrogen source, as it can be easily deprotected by treatment with thiourea.
