1,2-Disubstituted 4-quinolones have been prepared via copper-catalyzed heterocyclization of 1-(2-bromophenyl)- and 1-(2-chlorophenyl)-2-en-3-amin-1- ones, readily obtained from α,β-ynones and primary amines. The reaction tolerates a variety of useful functionalities including ester, keto, cyano, and chloro substituents. Quinolone derivatives can also be prepared via a sequential process from α,β-ynones and primary amines, omitting the isolation of the 1-(2-halophenyl)-2-en-3-amin-1-one intermediates.
