A novel and facile synthetic strategy for the construction of 1-benzazepines has been developed via copper-catalyzed oxidative C(sp)-H/C(sp)-H cross-coupling directly from two inert C-H bonds. This transformation represents an atom- and step-economical way to synthesize biologically important seven-membered benzo-heterocycles compared with the known methods.
