A direct two-step method for the preparation of 2-aryl- and 2-vinyl-4-quinolones that utilizes a copper-catalyzed amidation of ortho-halophenones followed by a base-promoted Camps cyclization of the resulting N-(2-keto-aryl)amides is described. With Cul, a diamine ligand, and base as the catalyst system, the amidation reactions proceed in good yields for a range of aryl, heteroaryl, and vinyl amides. The subsequent Camps cyclization efficiently provides the desired 4-quinolones using the conditions that are described.
