Abstract
Condensation reactions of 1,2,3,4-tetrahydro-6-methyl-2,4-dioxo-5-pyrimidinecarbaldehyde with nine acid derivatives containing an active methylene group are described. The obtained products were characterized by their IR, UV, 1 H NMR, 13 C NMR and mass spectra. The stereochemistry of selected products was studied by 1 H and 13 C NMR spectroscopy.
