Explored was the competitive ring-closing metathesis vs. ring-rearrangement metathesis of bicyclo[3.2.1]octenes prepared by a simple and convergent synthesis from bicyclic alkylidenemalono-nitriles and allylic electrophiles. It was uncovered that ring-closing metathesis occurs exclusively on the tetraene-variant, yielding unique, stereochemically and functionally rich polycyclic bridged frameworks
探索是有竞争力的闭环易位VS 。双环[3.2.1]辛烯的环重整易位反应,是由双环亚烷基丙二腈和烯丙基亲电体通过简单且收敛的合成方法制得的。据揭示,闭环复分解只发生在四烯变体,产生独特的立体化学和功能丰富的多环桥连的框架,而减少的版本(三烯)经历环重排易位到5 - 6 - 5个稠环体系类似于异戊烷核心。
