A simple and metal-free method has been developed for the construction of quinoline-2,4-carboxylates under mild conditions via a molecular iodine-catalyzed three-component tandem reaction of arylamines, ethyl glyoxylate, and alpha-ketoesters. The present protocol provides a convenient and attractive approach to various quinoline-2,4-carboxylates in moderate to good yields with excellent functional group tolerance.
