Abstract
Novel pyrano2,3-dpyrimidine-2,4,7-triones were synthesized in 90-97% yield via a three-component reaction of an aromatic aldehyde, Meldrums acid, and barbituric acid in the presence of 10 mol % K2CO3 under microwave irradiation. This is the first protocol to be reported for the synthesis of title compounds and the significant features of the present protocol are simplicity, high yields, short reaction time, involvement of aqueous work-up procedure, environmentally benign nature, and no chromatographic purification. © 2012 Elsevier Ltd.
