A new and convenient iron-catalyzed three-component tandem reaction of aromatic amines, glyoxylic esters, and α-ketoesters has been developed for the synthesis of quinoline-2,4-dicarboxylates under mild conditions. The present protocol, which utilizes cheap catalysts, readily-available starting materials and mild reaction conditions, provides an attractive approach to a series of functionalized quinoline

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.
