Z-Enediynes are prepared by a vicinal dialkynylation of triaryl(arylethynyl)phosphonium cations. The method, which proceeds under mild transition metal-free conditions, can be conducted on multigram scale as a one-pot, phosphine-mediated synthetic cycle giving enediyne products with excellent control of configuration.
Z-烯二炔是通过三芳基(芳基乙炔基)鏻阳离子的邻位二炔基化反应制备的。该方法在温和的无过渡金属条件下进行,可以以多克规模进行一锅法反应,通过膦介导的合成循环,以优异的构型控制得到烯二炔产物。
