Summary:Herein, we report an unprecedented aerobic copper-catalyzed [3+2] annulation reaction of diarylamines with indoles, which allows direct access to novel 2-diarylaminoindolo[2,3- b ]indoles, a class of potential photoelectric device molecules. The developed transformation proceeds with broad substrate scope, good functional group tolerance, high chemo-selectivity, and no need for pre-preparation of specific agents, which offers a practical route for diverse and atom-economic synthesis of the desired products that are difficult to prepare with the conventional approaches. Unprecedented direct access to novel 2-diarylaminoindolo[2,3- b ]indoles via aerobic copper-catalyzed [3+2] annulation of diarylamines and indoles is demonstrated.
