Condensation Reactions of 1,2,3,4-Tetrahydro-6-methyl-2,4-dioxo-5-pyrimidinecarbaldehyde

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, 1H NMR, 13C NMR and mass spectra. The stereochemistry of selected products was studied by 1H and 13C NMR spectroscopy.
