The synthesis of 11-methyl-6H-pyrido[4,3-b]carbazole-1(2H)-one (5), which can be important for the synthesis of other pyridocarbazole alkaloids and especially 1-substituted ellipticines, is described. Construction of the tetracyclic structure was achieved by a new route and two important precursor compounds (4a and 4b) for the synthesis of pyridocarbazole alkaloids and also many new tetrahydrocar-bazole
11-甲基-6 H-吡啶并[4,3 - b ]咔唑-1(2 H)-one(5)的合成对于其他吡啶并咔唑生物碱尤其是1-取代的玫瑰树碱的合成可能是重要的描述。四环结构的构建是通过一条新途径和两种重要的前体化合物(4a和4b)来合成的吡啶并咔唑生物碱以及许多新的四氢咔唑衍生物(7、8、9、10、11、12、13)被合成。
