摘要：
Oxalic acid catalyzed condensation of di(2-indolyl)methane with aromatic aldehydes has been established. Various indolo[2,3-b]carbazole derivatives were prepared in good isolated yields (up to 94.5%). Compared with literature methods, the present protocol features mild reaction conditions, easily controlled selectivity, good functional group tolerance, and simple operation procedures.
