Three-component [2 + 2 + 2] cycloaddition of terminal alkynes, internal alkynes, and terminal alkenes is achieved using an NbCl3(DME) catalyst, leading to 1,3,4,5-substituted 1,3-cyclohexadienes in excellent yields with high chemo- and regioselectivity.
使用NbCl 3(DME)催化剂可实现末端炔烃,内部炔烃和末端烯烃的三组分[2 + 2 + 2]环加成反应,从而获得极佳的1,3,4,5取代的1,3-环己二烯产生具有高化学选择性和区域选择性的产物。
