A series of carbazolone derivatives and 3-acetylindoles have been achieved via PIFA-mediated intramolecular cyclization of 2-aryl enaminones. This process allows the N-moiety on the side-chain to be annulated to the benzene ring via the metal-free oxidative aromatic CâN bond formation.
通过PIFA介导的2-芳基烯胺酮的分子内环化反应,成功合成了一系列咔唑酮衍生物和3-乙酰基吲哚。该过程实现了侧链上的N原子不经金属催化氧化即可芳构化并联接到苯环上,完成了芳香C-N键的构建。
