The Buchwald–Hartwig coupling/Michael addition sequence has been successfully applied to the synthesis of functionalized 1,2-disubstituted 4-quinolones using Pd(OAc)2 as a catalyst and PPh3 as a ligand. Under these conditions, the intermediate products first formed from chalcones and primary amines underwent catalytic dehydrogenation to yield the 1,2-disubstituted 4-quinolones.
Buchwald-Hartwig 偶联/迈克尔加成序列已成功应用于使用 Pd(OAc)2 作为催化剂和 PPh3 作为配体的功能化 1,2-二取代 4-喹诺酮类化合物的合成。在这些条件下,首先由查耳酮和伯胺形成的中间产物经过催化脱氢生成 1,2-二取代的 4-喹诺酮。
