DESs mediated three (or) four‐component one‐pot assembly of (E)‐4‐benzylidenylacridin‐1(2H)‐ones (E)‐2‐styryl quinoline‐3‐carboxamides is described. The method involves the consecutive three carbon–carbon and one carbon–nitrogen bond formation in a single reaction vessel. Moreover, gram scale synthesis and detailed mechanistic study have been established.
描述了一种由二铱(I)催化的DES介导的(E)-4-苄叉基ac啶-1(2H)-(E)-2-苯乙烯基喹啉3-羧酰胺的三(或)四组分单罐组装。该方法涉及在单个反应容器中连续形成三个碳-碳键和一个碳-氮键。此外,已经建立了克级合成法和详细的机理研究。
