The selective synthesis of substituted indoles was achieved by the ring-closing olefin metathesis (RCM)/elimination sequence or the RCM/tautomerization sequence of functionalized pyrrole precursors. The RCM/elimination sequence was also applied to double ring closure to yield a substituted carbazole.
通过闭环烯烃复分解(RCM)/消除序列或功能化吡咯前体的 RCM/互变异构序列,实现了取代吲哚的选择性合成。RCM/消除序列也被应用于双环闭环反应,得到取代咔唑。
