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。

Treatment of benzocyclobutenols substituted on the functional carbon by the NH3BF3-Et2O reagent allows the synthesis of the corresponding tertiary azides. The latter by acid-catalysed breakdown, lead to 2-substituted indoles. A similar result is obtained by treating directly the alcohols with hydrazoic add and concentrated sulfuric acid. This new route to indole nucleus is also extended to the synthesis
