Arylaminomethyl Radical-Initiated Cascade Annulation Reaction of Quinoxalin-2(1<i>H</i>)-ones Catalyzed by Recyclable Photocatalyst Perovskite

Abstract

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