A highly efficient protocol has been developed for the synthesis of diversely substituted isoindolo[2,1-b]isoquinolin-7(5H)-ones through sequential Cu(II)-catalyzed Sonogashira coupling, intramolecular hydroamidation followed by palladium-catalyzed ligand-free Heck reaction. Good to excellent yields (41–94%) were observed with excellent substrate scope and functional group tolerance. The developed
通过顺序的Cu(II)催化的Sonogashira偶联,分子内加氢酰胺化,然后钯催化的配体-合成了一种高效的协议,用于合成不同取代的isoindolo [2,1 - b ] isoquinolin-7(5 H)-ones。游离的Heck反应。观察到良好至优异的收率(41–94%),具有出色的底物范围和官能团耐受性。所开发的方法代表了构建生物活性异吲哚并[2,1 - b ]异喹啉-7(5 H)-ones的实用策略。
