Hexahydropyrrolo[3,2-[c] carbazole structure was constructed for the first time starting from ethyl 4-[oxo-[cyclohexanecarboxylate in seven steps. Some tetrahydrocarbazole derivatives (4, 5, 6, 7, 11, and 12) were also synthesized.EnglishDIELS-ALDER REACTIONASPIDOSPERMA ALKALOIDSCORE STRUCTUREIBOPHYLLIDINE SKELETONSTRYCHNOS ALKALOIDSVINCA ALKALOIDS(+/-)-DEETHYLIBOPHYLLIDINEANNULATIONPATHWAYArticle
