Abstract

A facile one-pot procedure for copper-catalyzed PhI (OAc) 2-mediated asymmetric alkene aziridination had been developed. Commercially available PhI (OAc) 2 and sulfonamides were used to generate the nitrene precursors (PhI NR) in situ for olefin aziridination. This one-pot procedure had been optimized using 4-nitrobenzenesulfonamide as the nitrene source. With 5mol% of the chiral copper catalyst, these conditions afforded 94% yield of ...
