Malonicacidresin 1 and the corresponding diester 2 have been used for the preparation of dihydropyrimidinones 6 and pyrimidinone carboxylic acids 8. Knoevenagel condensation of the unsymmetrical resin bound malonate diester 2 followed by condensation with amidines provides dihydropyrimidinone carboxylate esters 4. Cleavage of 4 with TFA afforded the carboxylic acid 5 which undergoes decarboxylation

protocols for synthesis of series of low-molecular-weight di- and tri-substituted pyrimidines bearing a functional group at the 4th position, which rely on a base-mediated condensation of amidines or guanidines with β-alkoxyvinyl α-keto esters, have been developed. This approach allowed for multigram preparation of novel pyrimidine-4-carboxylates in 21–90% yield. The synthetic utility of these compounds
