Abstract
Synthetic efforts towards new tetracyclic heterocycles bearing the pyrrolo[2′,3′:5,6]azepino[4,3-b]indol-4(11H)-one core are described. Synthesized tetracyclic compounds are the first analogs, structurally related to protein kinase inhibitors paullones which incorporate an azepinone, an indole and a pyrrole ring. The synthetic approach involves palladium mediated intramolecular Heck coupling as a key step.
摘要:描述了合成新的四环杂环化合物,其中含有吡咯并[2′,3′:5,6]氮杂杂二环[4,3-b]吲哚-4(11H)-酮核。合成的四环化合物是第一个类似于蛋白激酶抑制剂波隆酮的结构类似物,其中包括一个氮杂吲哚环、一个吲哚环和一个吡咯环。合成方法涉及钯介导的分子内Heck偶联作为关键步骤。
