A novel palladium(0)‐catalyzed intermolecular arylative dearomatization of α‐naphthols and subsequent aza‐Michael reaction is described. Two adjacent stereocenters were constructed efficiently through consecutive arylative dearomatization and Michael addition reactions. By utilizing this method, structurally diverse benzomesembrine derivatives were synthesized with excellent yields and chemoselectivity
描述了一种新型的钯(0)催化α-萘的分子间芳基脱芳香化反应以及随后的氮杂-迈克尔反应。通过连续的芳基脱芳香化反应和迈克尔加成反应,可以有效地构建两个相邻的立体中心。通过使用这种方法,合成了结构多样的苯甲mes衍生物,并具有优异的收率和化学选择性。苯甲膜产品被证明经历了多功能的官能团转化。
