摘要

The cyclodimerization of alpha,omega-allenynes using Cp* RuCl(cod) catalyst is described. This reaction proceeds via an alkylidene ruthenacyclopentene intermediate, which is generated by the oxidative cycloaddition of alkyne and the internal double bond of the allene, to give a unique pentacyclic compound having two five-membered rings and three four-membered rings in high yields.
