A rhodium-catalyzed annulation of 3-(1H-indol-3-yl)-3-oxopropanenitriles with sulfoxonium ylides or diazo compounds has been developed, leading to a series of polysubstituted carbazoles in moderate to good yields. This procedure proceeded with formal Rh(iii)-catalyzed (4 + 2) cycloaddition, with the functionalization of 2-C-H bonds of indole in a step-economical procedure. Additionally, this reaction could also be conducted under acidic conditions when diazo compounds were employed as the reaction partners, which was a complement to the annulation of sulfoxonium ylides under weak basic conditions.
