A library of 72 quinolones was synthesized from substituted anthranilic acids, using ynone intermediates. These masked beta-dicarbonyl synthons allowed cyclization under milder conditions than previously reported quinolone syntheses. (C) 2009 Elsevier Ltd. All rights reserved

A novel method of palladium-catalyzed oxidative carbonylation of ketones, amines, and carbon monoxide for the synthesis of 4-quinolones has been developed. This protocol provides a straightforward route to construct useful 4-quinolone derivatives from inexpensive chemicals.
