A palladium‐catalyzed inert C−H bond activation and cyclocarbonylation of isoquinolones leading to isoindolo[2,1‐b]isoquinoline‐5,7‐diones under 1 atm of carbon dioxide has been developed. This transformation features high regio‐ and chemo‐selectivity, step‐economy, and good functional group tolerance. Most of the corresponding products were obtained in moderate to good yields. It offers an alternative
已开发出在1个大气压的二氧化碳下,钯催化的惰性C-H键活化和异喹诺酮的环羰基化反应,导致异吲哚并[2,1 – b ]异喹啉-5,7-二酮。这种转变具有很高的区域选择性和化学选择性,逐步经济性和良好的官能团耐受性。大部分相应的产品以中等到良好的产率获得。它为合成有用的多种异吲哚并[2,1 - b ]异喹啉-5,7-二酮衍生物提供了另一种方法。
