The combination of ring-closing metathesis (RCM) followed by an intramolecular Pauson–Khand reaction gives direct entry to tricyclic compounds. The RCM was carried out on a hexacarbonylcobalt-complexed alkyne, this complex acting as a protecting group against enyne metathesis. The procedure was studied for dienynes containing heteroatoms and allows the building of [6,5,5] and [7,5,5] tricyclic systems
闭环复分解 (RCM) 和分子内 Pauson-Khand 反应的组合可以直接进入三环化合物。RCM 在六羰基钴络合的炔烃上进行,该络合物充当防止烯炔复分解的保护基团。该程序针对含有杂原子的二炔进行了研究,并允许构建 [6,5,5] 和 [7,5,5] 三环系统。该工艺的可行性在很大程度上取决于基材的性质。 (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
