摘要: An efficient copper-catalyzed in situ C-(sp 2 )-NH bond formation to provide a range of 3-aminoquinolin-2(1H)-ones and 3-aminocoumarins from 3-bromoquinolinones 3-bromocoumarins, respectively, has been achieved. The reaction conditions involve the use copper powder as catalyst, eco-friendly ethanol solvent presence pipecolinic acid ligand ascorbic additive. efficiency this practical method was demonstrated synthesis various anilines.
