An efficient carbonylative procedure for the synthesis of 3-arylquinoin-2(1H)-ones has been established. Through a palladium-catalyzed aminocarbonylation of benzylchlorides with anthranils, a variety of 3-arylquinoin-2(1H)-one products were obtained in moderate to excellent yields with good functional group tolerance.

The invention provides macrocyclic compounds inhibitory to the Hepatitis C viral protease, compositions and combinations including the compounds, methods of treatment of conditions wherein inhibition of the Hepatitis C viral protease is medically indicated, and methods of treatment of a Hepatitis C viral infection in a human patient.
A facile synthesis of various functionalized 3-substituted quinolin-2(1H)-ones through Ag(I) nitrate-catalyzed cyclization of o-alkynylisocyanobenzenes is described. The reaction allows rapid and convenient access to 3-substituted quinolin-2(1H)-one scaffolds in moderate to good yields.
A palladium-catalyzedcarbonylative cyclization of benzylchlorides with o-nitrobenzaldehydes has been developed for the synthesis of 3-arylquinolin-2(1H)-ones. Mo(CO)6 played a dual role as both a CO surrogate and a reductant in this carbonylative transformation.

Alcohols are used as accessible and safe C-alkylation agents to produce α-functionalized nitriles or oxindoles and 2-quinolinones via borrowing hydrogen strategy mediated by a [Mg4Al-LDH]-supported silver nanoparticle catalyst. Combination of a suitable basic LDH support together with homogeneously distributed silver metallic centers are the key elements for the success of the protocol.
