Abstract

Organic azides play important roles in synthetic chemistry, chemical biology, drug discovery, and material science. Azido-functionalization of alkenes is one of the most efficient procedures for rapid introduction of azide group into organic compounds. But only a few examples have been documented in the catalytic asymmetric version of the azidation of alkenes. Herein, we report an unprecedented highly diastereo- and enantioselective bromoazidation of α,β-unsaturated ketones catalyzed by chiral N,N'-dioxide/Fe(OTf)
