A new approach to the synthesis of cyclopenta[g]indole derivatives possessing structural features of natural alkaloids, such as trikentrins and herbindols, is described. The key step in the sequence is a thallium(III)-mediated ring-contraction reaction to transform a cyclohexene moiety into a functionalized cyclopentyl unit.
本文介绍了一种合成环戊并[g]吲哚衍生物的新方法,这种衍生物具有天然生物碱的结构特征,例如三尖杉酯和草本吲哚。其中的关键步骤是通过铊(III)介导的缩环反应将环己烯分子转化为官能化环戊基单元。
