Reaction of 1-benzenesulfonylindole-2,3-dicarboxylic anhydride with wittig reagents: Synthesis of pyrrolo[1,2-a]-indoles and cyclopent[b]indole

Treatment of 1-benzenesulfonylindole-2,3-dicarboxylic anhydride with methylenetriphenylphosphorane gave the corresponding ylide. After esterification of the carboxyl group and removal of the benzenesulfonyl group of the ylide, the obtained ylide was react
