| Abstract: | 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. |
