Four parent carbolines and the corresponding 5- or 9-methylsulfonyl derivatives were synthesized by the palladium-catalyzed intramolecular arylation reaction of ortho-bromo-substituted anilinopyridines which were prepared by the palladium-catalyzed amination reaction of iodobenzenes with aminopyridines. Carbazole and its 9-methylsulfonyl derivative were also synthesized by the same method.
通过钯催化的碘代苯与氨基吡啶的胺化反应制备邻溴代苯胺基吡啶,再经钯催化的分子内芳基化反应合成了四个母体咔啉及其相应的5-或9-甲基磺酰基衍生物。采用相同方法也合成了咔唑及其9-甲基磺酰基衍生物。
