A general strategy to synthesize bridged polycyclic molecules is presented. The synthesis is accomplished via a cascade reaction initiated by rhodium carbene formation. Subsequent intramolecular reaction with an alkyne is then followed by a transannular C–H bond insertion. A rationale for prediction of the major structural isomer that is formed is described and applied to a wide variety of substrates
提出了合成桥联多环分子的一般策略。合成通过铑卡宾形成引发的级联反应完成。随后,与炔烃的分子内反应随后是跨环的C–H键插入。描述了预测所形成的主要结构异构体的原理,并将其应用于多种底物。该原理基于基板中环系统的构象和立体电子方面的考虑。
