A CuH‐catalyzed enantioselective hydroamidation reaction of vinylarenes has been developed using readily accessible 1,4,2‐dioxazol‐5‐ones as electrophilic amidating reagents. This method provides a straightforward and efficient approach to synthesize chiral amides in good yields with high levels of enantiopurity under mild conditions. Moreover, this transformation tolerates substrates bearing a broad

A method for enantioselective intermolecular benzylicC−H amidation and amination is reported. This dehydrogenative C−N bond formation displays broad substrate scope and good atom economy, is amenable to late-stage C−H functionalization, and enables easy access to 15N-labeling from cheap [15N]-NH4Cl.
