Herein, we describe a practical method for the preparation of the 6H-dibenzo[b,h]carbazole scaffold by utilizing a Pd-catalyzed intramolecular amination of 3-amino-3′-bromo-2,2′-binaphthyl. X-ray analysis revealed that the naphthalene wings of the 6H-dibe

A visible-light-accelerated Rh(III)-catalyzed C-H annulation of aromatic amines with bicyclic alkenes for the synthesis of benzocarbazole derivatives was developed. In this approach, with the cooperation of rhodium catalysis and visible-light irradiation, various aromatic amines reacted with oxabicyclic alkenes and azabicyclic alkenes smoothly at room temperature, delivering the corresponding bridged oxa or aza tetrahydro benzocarbazoles in good to excellent yields. Moreover, a series of benzo[b]carbazoles were synthesized conveniently through further aromatization in one pot. The potential of this method was demonstrated via directing-group removal, derivatization, a scale-up reaction, and fluorescence investigations.
