  Reaction of 1-Benzenesulfonylindole-2,3-dicarboxylic Anhydride with Wittig Reagents: Synthesis of Pyrrolo[1,2-a]indoles and Cyclopent[b]indole

  摘要：

  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 reacted with aldehydes to yield alpha,beta -unsaturated ketones, which were converted to pyrrolo[1,2-a]indoles. We also examined the reactivity of the anhydride with (carbethoxymethylene)triphenylphosphorane and (carbethoxyethylidene)triphenylphosphorane.
