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
