Abstract
Abstract An efficient [4+2] cyclization of N -methylanilines with maleimides to afford tetrahydroquinolines using N -hydroxyphthalimide as a metal-free and cheap organophotoredox catalyst is reported. The protocol involves C(sp 3 ) H activation of N -methylanilines for the formation of α-amino radical without an oxidant at room temperature. The present method describes an easy preparation of tricyclic heterocycles in good to excellent yields under mild reaction conditions.
