[5,n] bicyclic systems with cis ring junction stereochemistry were accessed readily through RRM (ring rearrangement metathesis) reaction of properly functionalized [2.2.1]norbornene skeletons. Several bicyclic enones, ketones, alcohols, and ethers acted as the substrates and yielded the respective linearly fused [5,n] bicyclic systems stereoselectively after the RRM reaction. Such [5,5]bicyclic enone
通过具有适当功能的[2.2.1]降冰片烯骨架的RRM(环重排易位)反应,可以轻松地访问具有顺式环结立体化学结构的结构多样的[5,n ]双环系统。几种双环烯酮,酮,醇和醚充当底物,并在RRM反应后立体选择性地生成了各自的线性稠合[5,n ]双环系统。例如[5,5]双环烯酮的支架然后合成操纵以天然存在的具有衬垫triquinane hirsutene芯结构类似物顺式-顺式-顺式立体化学。
