Abstract

A catalytic synthetic approach is described for preparing 2-quinolinone compounds through a Pd-catalyzed C([sp.sup.2])-H functionalization/intramolecular amidation sequence. The cyclization process is shown in the presence of a catalytic amount of Pd[Cl.sub.2] and Cu[(OAc).sub.2] under an [O.sub.2] atmosphere, which has provided access to various substituted 4-aryl-2-quinolinones.

Abstract

A catalytic synthetic approach for the synthesis of 2-quinolinone compounds through a Pd-catalyzed C(sp2)-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 O2 atmosphere, providing practical access to a range of variously substituted 4-aryl-2-quinolinones.

11. Palladium-catalyzed C-H activation/intramolecular amination reaction: a new route to 3-aryl/alkylindazoles.

Abstract

A method for the catalytic C-H activation of hydrazone compounds followed by intramolecular amination is described. It requires the use of a catalytic amount of Pd(OAc)2 in the presence of Cu(OAc)2 and AgOCOCF3, which efficiently effects the cyclization to afford variously substituted indazoles. The reactions proceed under relatively mild conditions and thus tolerate a variety of functional groups, including alkoxycarbonyl and cyano groups and halogen atoms.
