The FeCl3/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.

Flash vacuum pyrolysis of 4-methoxystyrylarenes (1b-e) at 800°C and ca. 1×10-2 Torr gave the corresponding areno[e]indenes (3b-e) as the major products and 4-hydroxystyrylarenes (4b-e) as the miner ones.
