A feasible arylaminomethyl radical-triggered tandem annulation reaction has been developed toward a large variety of poly fused heterocycles, tetrahydroimidazo[1,5-a]quinoxalin-4(5H)-ones, by reacting diverse quinoxalin-2(1H)-ones with various N-arylglycines in green solvent (DMC) in the presence of CsPbBr3 under white-light irradiation conditions.
