A copper-catalyzedoxidative cyclization of vinyl azides with benzylic Csp3–H bonds via a tandem dual C–H functionalization process has been developed. This procedure allows access to substituted phenanthridines containing a variety of functional groups. In addition to benzyl hydrocarbons, other substrates containing unactivated Csp3–H bonds, such as ethers and alkanes could also be applied successfully
