(Figure not available: see fulltext.)The synthesis of polysubstituted tetrahydropyrimidines (dimethyl/diethyl-1,3-disubstituted-1,2,3,6-tetrahydropyrimidine-4,5-dicarboxylate) derivatives from but-2-ynedioates, amines, and formaldehyde via a one-pot multicomponent reaction is reported. The reactions were performed under solvent-free and mild conditions with shorter reaction times, high purity, and high yield. The obtained products are interesting heterocyclic compounds containing ester functional groups and exhibited excellent antibacterial activity and moderate-to-good antioxidant properties.
