The gold-catalysed direct couplings of indoles 1 and pyrroles 5 with 1,3-dicarbonyls 2 is described. This new method for CC bond formation allows high functional group tolerance, regioselectivity, and scope under relatively mild conditions. Moreover, the 3-alkenylindoles 3 can be readily available through gold-catalysed sequential cyclization/alkenylation reaction of 2-alkynylanilines derivatives 4
描述了吲哚1和吡咯5与1,3-二羰基2的金催化的直接偶联。这种形成CC键的新方法可在相对温和的条件下实现较高的官能团耐受性,区域选择性和范围。而且,通过2-炔基苯胺衍生物4与1,3-二羰基2的金催化的顺序环化/烯基化反应,可以容易地获得3-烯基吲哚3。
