A novel strategy for the synthesis of 3-methylene-2-arylisoindolin-1-ones through Sonogashira cross-coupling/nucleophilic addition reactions using calcium carbide as a surrogate of gaseous acetylene, 2-bromo-N-(2-bromophenyl)benzamide substrates as starting materials, and copper as a catalyst was described. The salient features of this protocol are the use of a readily available and easy-to-handle
一种通过 Sonogashira 交叉偶联/亲核加成反应合成 3-methylene-2-arylisoindolin-1-ones 的新策略,使用碳化钙作为气态乙炔、2-溴-N-(2-溴苯基)苯甲酰胺底物的替代物作为起始材料,铜作为催化剂进行了描述。该协议的显着特点是使用现成且易于处理的炔烃源、广泛的基板范围、露天条件、水系统和简单的操作程序。此外,这种方法可以扩大到克规模。
