  Intermolecular benzyne cycloaddition (IBC), a versatile approach to benzophenanthridine antitumor alkaloids. Formal synthesis of nitidine and chelerythrine

  摘要：

  A new approach to the synthesis of benzophenanthridine alkaloids is described which is based on cycloaddition of arynes to pyrrolinediones, the pyrrolinediones behaving as aza diene equivalents. The synthesis of 2,3,8,9-substituted benzophenanthridines and the regioselective synthesis of a 2,3,7,8-substituted benzophenanthridine were performed. The formal synthesis of chelerythrine and the antitumor alkaloid nitidine is described.
