detailed our synthesis of the gambierol A-C and F-H ring precursors. Reported herein is a description of the coupling of the two precursors and the conversion of the coupled material into gambierol. Coupling of the subunits involved ester formation, enol ether RCM, and mixed thioketal formation and reduction. By employing this strategy we were able to bring highly advanced subunits into the coupling and, as
上一手稿详细介绍了我们的甘比罗尔AC和FH环前体的合成。本文报道了两种前体的偶合以及偶合的材料向甘菊醇的转化的描述。亚基的偶联包括酯的形成,烯醇醚的RCM以及硫代缩酮的混合形成和还原。通过采用这种策略,我们能够将高度先进的亚基引入偶联反应,因此,我们能够最大程度地减少完成甘比罗尔所需的偶联后转化的次数。合成完成后,我们以44个步骤(最长的线性序列)产生了7.5 mg(1.5%的总收率)的(-)-gambierol。
