In this paper, a novel Rh(I)-catalyzed Pauson–Khand-type [3 + 2 + 1] cycloaddition reaction of ene-vinylidenecyclopropanes (Ene-VDCPs) and carbon monoxide (CO) has been developed to furnish a series of aza- and oxa-bicyclic compounds in moderate to good yields in a highly regio- and diastereoselective manner, which provides an alternative and efficient synthetic approach for the access of bicyclic
在本文中,开发了一种新型的Rh(I)催化的烯-亚乙烯基环丙烷(Ene-VDCPs)和一氧化碳(CO)的Pauson-Khand型[3 + 2 + 1]环加成反应,以提供一系列的氮杂-和氧-双环化合物以高区域选择性和非对映选择性的方式以中等至良好的收率收率,这为双环环己酮骨架的获得提供了另一种有效的合成方法。讨论了基材的范围和局限性以及合理的机制。
