Intramolecular amination copper-catalyzed indole synthesis

The intramolecular amine-halogen copper-promoted indohzation was applied to the synthesis of more-complex indoles (Scheme , equations 1 ) [58-61]. Other examples in this category of copper-catalyzed amination are syntheses of the carbazole alkaloids murrayaquinone-A and ( )-bis-murrayaquinone-A [62], 3-aryl p-carbolin-l-ones [63, 64], carbazoles from donble C-N cyclization [65], pyrrolo[2,3-c]...
