摘要：

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