A simple and practical method has been developed based on intermolecular [Pd]-catalyzed C–C and an intramolecular [Cu]-catalyzed C–O bond formations for the synthesis of flavans and benzoxepines. Interestingly, the method is amenable for the synthesis of a wide variety of flavans and benzoxepines with dense functionalities on aromatic moieties. Significantly, flavans and benzoxepines are present as
基于分子间[Pd]催化的C–C和分子内[Cu]催化的C–O键的形成,开发了一种简单而实用的方法,用于合成黄烷和苯并氧杂松。有趣的是,该方法适用于合成在芳族部分上具有致密官能团的多种黄烷和苯并二氢吡啶。值得一提的是,黄烷和苯并xepine以许多生物活性天然产物的核心/部分结构形式存在。
