A highly efficient TfOH-catalyzed addition of C3-substituted indole derivatives with (1H-indol-2-yl)diphenyl-methanols has been established, leading to the synthesis of a series of potentially bioactive 2,3'-bisindols in moderate to high yields (48%~89%) and with broad substrate scope under mild conditions. In addition, the furan-2-yldiphenylmethanol could also be applied in the reaction and afforded 2-(5-benzhydrylfuran-2-yl)-1H-indole in good yield.

Key words: addition reaction, synthetic method, 2,3'-bisindole derivatives, (1H-indol-2-yl)diphenylmethanol, TfOH
