Domino metathesis involving ring-opening metathesis–ring-closing metathesis (ROM–RCM) of a bicyclo[2.2.2]octene derivative having an appropriate alkene chain, expected to produce a 7/6 fused bicyclic system, provided a decalin system in contrast to ROM–RCM of the corresponding bicyclo[2.2.1]heptene analogues, which as expected produced the 7/5 fused bicycles. The expected 6/7 bicyclic system could
相反,涉及具有适当烯烃链的双环[2.2.2]辛烯衍生物的开环易位-闭环易位(ROM-RCM)的多米诺斯复分解提供了十氢化萘体系,相反,该双环[2.2.2]辛烯衍生物具有适当的烯烃链ROM-RCM中相应的双环[2.2.1]庚烯类似物的合成,该化合物有望生产出7/5融合自行车。但是,预期的6/7双环系统可以通过RCM来实现,该RCM是由相同的双环[2.2.2]辛烯类似物通过非代谢途径制备的可擦除ROM产品。提出了解释这两种系统对ROM-RCM的反应模式差异的基本原理。
