NbCl3-Catalyzed Intermolecular [2+2+2] Cycloaddition of Alkynes and alpha,omega-Dienes: Highly Chemo- and Regioselective Formation of 5-(omega-Alkenyl-1,4-substituted-1,3-cyclohexadiene Derivatives
[摘要]：Intermolecular [2+2+2] cycloaddition of tert-butylacetylene with alpha,omega-dienes was successfully achieved by NbCl3(DME) catalyst to afford 5-omega-alkenyl-1,4-disubstituted-1,3-cyclohexadienes in excellent yields with high chemo- and regioselectivity.
