A tandem transformation of C-N coupling/C-H carbonylation has been developed for the synthesis of benzo-1,4-oxazepine pharmaceutically derivatives. Notably, this reaction was accomplished by various phenylamine with ally halides under carbon dioxide atmosphere employing 2-(2-dimethylamino-vinyl)-1H-inden-1-olcatalyzed. Furthermore, under the optimized conditions, various benzo-1,4-oxazepine derivatives
已经开发了CN偶联/ CH羰基化的串联转化,用于合成苯并-1,4-氧杂ze庚因药物衍生物。值得注意的是,该反应是通过在2-(2-二甲基氨基-乙烯基)-1H-茚满-1-醇催化下在二氧化碳气氛下用各种苯胺与烯丙基卤完成的。此外,在优化的条件下,以良好的收率获得了各种苯并-1,4-氧杂氮杂卓衍生物。最后,提出了一种可行的CN偶联/ CH羰基化转化的CuI / CuIII机理。
