A regioselective synthesis of 2,5-disubstituted furans using copper(I) catalyst from haloalkynes in a one-pot procedure has been reported. This chemistry proceeds through the hydration reaction of 1,3-diynes, which can be readily prepared from the coupling reaction of haloalkynes in the presence of CuI. The procedure also can be used for the facile synthesis of 2,5-disubstituted thiophenes.
已经报道了使用一锅法从卤代炔烃中使用铜(I)催化剂进行区域选择性合成2,5-二取代的呋喃。该化学过程是通过1,3-二炔的水合反应进行的,这很容易从卤代炔在CuI存在下的偶联反应中制备。该方法还可用于2,5-二取代噻吩的简便合成。
