A visible‐light‐induced photocatalytic aerobic oxidation/[3+2] cycloaddition/aromatization cascade between secondary amines and isocyanides has been successfully developed. The reaction provides a general and efficient access to diversely substituted imidazoles and imidazo[1,5‐a]quinoxalin‐4(5 H)‐ones in good yields under mild conditions.
仲胺和异氰酸酯之间的可见光诱导的光催化需氧氧化/ [3 + 2]环加成/芳构化级联反应已成功开发。该反应可在温和条件下以高收率普遍有效地获得各种取代的咪唑和咪唑并[1,5 - a ]喹喔啉-4(5 H)-酮。

essential requirement of transition metal catalysts and chemical oxidants. A wide variety of different functionalities are well tolerated under this reaction condition, contributing to the substrate scope and applicability. Several control experiments and cyclic voltammetry studies suggest an electro-oxidation triggered successive C−C and C−Nbondformations followed by rapid aromatization for constructing
