A synthetic way for the construction of the tetracyclic 1,2,3,4,5,6-hexabydro-1,5-methanoazocino[4,3-b]indo1e system I, having a methoxycarbonyl substituent at the C-6 position, is reported. The synthesis implies methoxycarbonylation of the Interannular methylene carbon of an appropriate 2-(4-pyridylmethyl)indole, followed by alkylation of the pyridine nitrogen, catalytic hydrogenation and, finally
构造四环1,2,3,4,5,6-hexabydro-1,5-methanoazocino [4,3- b ]
吲哚体系I的合成方法,该化合物在C-6位具有甲氧羰基取代基,被报道。该合成意味着适当的2-(4-
吡啶基甲基)
吲哚的环间亚甲基碳的甲氧基羰基化,随后是
吡啶氮的烷基化,催化氢化,最后是所得2-(4-
哌啶基甲基)
吲哚的氧化环化。
