Abstract
Abstract Microwave-assisted three-component cyclocondensation of barbituric acids 1 , benzaldehyde 2 and alkyl nitriles 3 proceeds in the absence or presence of triethylamine to afford pyrano[2,3-d]pyrimidines 4 and 6-aminouracils 5 or 6-hydroxyaminouracils 6 react with 2 and 3 under identical conditions to yield pyrido[2,3-d]pyrimidines 7 , all in high yields.
