A novel ruthenium-catalyzed carbon-carbon bond formation between propargylic alcohols and alkenes via the allenylidene-ene reaction has been found to afford the corresponding 2,4-disubstituted-1-hexen-5-ynes in moderate yields. The finding described here discloses a new reactivity of allenylidene complexes. As a synthetic application, intramolecular cyclization of propargylic alcohols bearing an alkene
已经发现一种新型钌催化的炔丙醇和烯烃之间通过亚丙叉-烯反应形成的碳-碳键以中等产率提供相应的 2,4-二取代-1-己烯-5-炔。这里描述的发现揭示了亚丙叉基配合物的新反应性。作为一种合成应用,已经开发出带有烯烃部分的炔丙醇的分子内环化,以高产率得到相应的顺式取代色满,并具有优异的非对映选择性。
