Rhodium (Rh)‐catalysed [4+2] annulation of aromatic oximes with common terminal alkenes for the synthesis of 3,4‐dihydroisoquinolines is presented. Through the cooperation of a Rh(III) catalyst and a catalytic amount of K2HPO4 base, the reaction enables the formation of two new bonds, a C(sp2)−C(sp3) bond and a C(sp3)−N bond, in a single reaction via functionalization of both the C−H and N−O bonds
