reaction with 2-keto-1,3-indandiones. The application of this methodology has been demonstrated for the synthesis of the 6/6/5/6/6 scaffold of rubialatin A. 1H NMR experimental studies confirm that the reaction proceeds through the formation of benzocyclobutane followed by a 7-member carbocycle ring.
在温和的无过渡金属条件下,通过芳烃插入反应与 2-keto-1,3-indandiones 合成了二苯并双环[3.2.1]octadienone 支架,该支架已在萘环素、engelharquinones、rubialatin A 等中发现。该方法的应用已被证明可用于合成 rubialatin A 的 6/6/5/6/6 支架。1 H NMR 实验研究证实,该反应通过形成苯并环丁烷和 7 元碳环进行.
