An efficient and convenient method enabling direct amination of unactivated methylene C­(sp3)–H bonds to form C–N bonds with azodiformates as amino source is described. This method highlights the emerging strategy of unactivated methylene as versatile functional groups in organic synthesis and provides a strategy to construct functionalized C–N bonds for the synthesis of complex molecules.
