摘要

The one-pot synthesis of pyrido[2,3-d]pyrimidine derivatives has been reported viaKnoevenagel-Michal addition pathways using substitutedaromatic aldehydes, Cyanoacetamide and 6-aminouracilin N,N-dimethylformamide (DMF) solvent, with4-dimethylaminopyridine (DMAP) as new organo catalystcatalyst under ultrasonic irradiation. The results showedthat a series of aromatic aldehydes were effectively used toprepare the targeted pyrido [2, 3-d] pyrimidine derivativeswith good to excellent yields (81-93 %) with no major effecton the yield of product by electron donating/withdrawingsubstituents. Short reaction time, environment friendlyprocedure, excellent yields, inexpensive and readilyavailable catalyst are the advantages of this procedure.All synthesized compounds were characterized by IR,1HNMR, 13CNMR and mass spectral data.
