1′-biphenyl]-2-carboxylic acids, a series of polycyclic compounds possessing an altenuene backbone were obtained in moderate to good yields. The Umpolung diesterification reaction was completed under mild reaction conditions without an additional nucleophilic reagent. This work offers a concise method for the synthesis of diverse natural altenuene analogues. The mechanism was proposed, and the [1,5]-H shift was studied
通过PhI(OAc) 2氧化脱芳构化和3'-羟基-[1,1'-联苯]-2-羧酸的二酯化,以中等至良好的收率获得了一系列具有链烯骨架的多环化合物。Umpolung 二酯化反应在温和的反应条件下完成,无需额外的亲核试剂。这项工作为合成多种天然altenuene 类似物提供了一种简洁的方法。提出了该机制,并通过计算研究研究了从酮型结构到苯酚的异构化过程中的 [1,5]-H 位移。
