A catalytic synthetic approach for the synthesis of 2-quinolinone compounds through a Pd-catalyzed C(sp2)−H functionalization/intramolecularamidation sequence is described. The cyclization process efficiently proceeds in the presence of a catalytic amount of PdCl2 and Cu(OAc)2 under an O2 atmosphere, providing practical access to a range of variously substituted 4-aryl-2-quinolinones.

Diverse 4‐aryl‐2‐quinolinones are prepared from propionamides in one pot by ligand‐promoted triple sequential CH activation reactions and a stereospecific Heck reaction. In these cascade reactions, three new CC bonds and one CN bond are formed to rapidly build molecular complexity from propionic acid.
通过配体促进的三重连续 C - H 活化反应和立体特异性 Heck 反应,由丙酰胺一锅制备多种 4-芳基-2-喹啉酮。在这些级联反应中,形成了三个新的 C → C 键和一个 C → N 键,从而由丙酸快速构建分子复杂性。
