Synthetic Approach to Dictyodendrins: A Facile Synthesis of Pyrrolo[2,3-c]carbazole, Pyrrolodibenzothiophene, and Benzo[e]indole
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.
Synthesis of 3-indolylpyrroles via base-mediated cycloaddition of TOSMIC with activated indole-2/3-vinylenes
