We successfully developed a nickel-catalyzed transamidation method for the ring opening of N-acyl lactams. The method involves a reaction between N-benzoylpyrrolidin-2-one derivatives and aniline derivatives, with Ni(PPh3)2Cl2 serving as the catalyst, 2,2′-bipyridine as the ligand, and manganese as the reducing agent. This reaction led to the formation of ring-opening-amidated products in good yields
我们成功开发了镍催化N-酰基内酰胺开环转酰胺基化方法。该方法以Ni(PPh 3 ) 2 Cl 2为催化剂,2,2'-联吡啶为配体,锰为还原剂,由N-苯甲酰吡咯烷-2-酮衍生物与苯胺衍生物反应。该反应以良好的产率形成了开环酰胺化产物。值得注意的是,该方法在生产各种环尺寸的相应开环转酰胺基产物(包括四元环、五元环、六元环、七元环和八元环内酰胺)方面表现出优异的效率。
