A highly efficient palladium-catalyzed cascade annulation of 2-vinylbenzaldehydes with indoles was achieved to afford 6-(3-indolyl)benzo[b]carbazoles I [R = H, 8-MeO, 8,9-di-F, etc.; R1 = H, 1-MeO, 2-F, etc.; R2 = H, 4-MeO, 5-Cl, etc.] under mild conditions in good yield and with excellent regioselectivity. Mechanistic investigations reveal that the reaction proceeded via double addition of indoles, unexpected intramol. 1,4-aryl and 1,2-hydrogen migrations and oxidative aromatization.
