An intramolecular hydroamidation of ortho-vinyl benzamides had been developed. The reaction was promoted efficiently by potassium tert-butoxide and N,N-dimethylformamide without the need for strong oxidants or transition-metal catalysts. A series of dihydroisoquinolinones and 3-benzylisoindolinones were prepared in good to excellent yields. The new method is operationally simple, scalable, and tolerant
已经开发了邻乙烯基苯甲酰胺的分子内加氢酰胺化。叔丁醇钾和N,N-二甲基甲酰胺可有效促进反应,而无需强氧化剂或过渡金属催化剂。制备了一系列二氢异喹啉酮和3-苄基异吲哚啉酮,收率良好至优异。新方法在操作上简单,可扩展并且可以容忍各种功能组。
