An original tribromide derivative based, palladium-catalyzed synthesis of 3-substituted-1(2H)-isoquinolone is described based on a regioselective Suzuki–Miyaura C–C coupling on o-halo-(2,2-dihalovinyl)-benzene followed by a palladium catalyzed amination–carbonylation–cyclization reaction. This sequence efficiently proceeds to build up isoquinolone in fair to good yields over a one-pot 3-bond synthesis reaction.
报道了一种基于三溴衍生物的钯催化合成3-取代-1(2H)-异喹啉酮的方法,该方法基于在邻卤-(2,2-二卤乙烯基)-苯上选择性Suzuki-宫浦C-C偶联反应,然后通过钯催化的氨基化-羰基化-环合反应实现。该反应序列通过一次三键合成反应高效地构建异喹啉酮,产率中等至良好。
