The FeCl 3 /DDQ‐PTSA/NBS‐mediated cyclization (DDQ = 2,3‐dichoro‐5,6‐dicyano‐1,4‐benzoquinone, PTSA = p ‐toluenesulfonic acid, NBS = N ‐bromosuccinimide) of 2‐arylvinyl‐3‐indolylpyrrole led to the formation of the pyrrolo[2,3‐ c ]carbazole core unit of dictyodendrins in yields of 75–90 %. The cyclization method was also successfully applied to the syntheses of pyrrolodibenzothiophene and benzo[ e ]indole derivatives.
