The first copper‐catalyzed asymmetric cyanation and etherification reactions of enamides have been established, where a carbon‐centered radical adjacent to a nitrogen atom (CRAN) is enantioselectively trapped by a chiral copper(II) species. Moreover, the asymmetric cyanation of vinyl esters was disclosed as well. These reactions feature very mild reaction conditions and high functional group tolerance
