of cyclopropanes was developed by gold-catalyzed cycloisomerization of 2-(1-alkynyl-cyclopropyl)pyridine with nucleophiles, which provides efficient access to structurally diverse indolizines under mild conditions. A series of N-, C- and O-based nucleophiles were involved in this reaction to afford the corresponding indolizines in modest to excellent yields.
通过亲核试剂通过金催化的2-(1-炔基-环丙基)吡啶与亲核试剂的环异构化反应,开发了一种新型的环丙烷CC键断裂方法,该方法可在温和条件下有效地获得结构多样的吲哚嗪。该反应涉及一系列基于N,C和O的亲核试剂,以中等至极好的收率提供了相应的吲哚嗪。
