afforded the first practical, one-pot and general approach towards synthesis of N-(un)substituted isoquinolin-1(2H)-ones. Both the catalyst and the solvent used are recyclable. The use of the Cu reagent in excess led to the unusual formation of regioisomeric and uncommon isoquinolin-1(4H)-ones.
配体/添加剂/无Pd的铜介导的偶联/环化策略为合成N-(未)取代的异喹啉-1(2H)-酮提供了第一个实用的,一锅通用的通用方法。所用的催化剂和溶剂都是可回收的。过量使用铜试剂会导致区域异构和不常见的异喹啉-1(4H)-1的异常形成。
