Revised: The total synthesis of gomerone C results in revision of the stereochemical assignment at C3 (see scheme). The synthetic strategy relies on a late‐stage Conia‐ene reaction, which efficiently forms the bicyclo[3.2.1]octane containing the bridgehead chloride and generates an exocyclic olefin, which can be used as a flexible handle for further elaboration. The two contiguous quaternary centers
已修订:Gomerone C的总合成导致C3处立体化学赋值的修订(请参阅方案)。合成策略依赖于后期的Conia-ene反应,该反应可有效形成含有桥头氯化物的双环[3.2.1]辛烷,并生成环外烯烃,可用作进一步处理的灵活方法。两个相邻的四元中心是通过Diels-Alder反应安装的。
