1,4-Dihydropyrimidines were synthesized by reductive dethionation of the corresponding 2-thiono-4-aryl-1,2,3,4-tetrahydropyrimidine-5-carboxylic acid derivatives, and some of their properties were studied.doi:10.1007/BF00478132E. L. Khanina...
The oxidation of derivatives of 2-oxo-4-phenyl-6-methyl-1,2,3,4-tetrahydropyrimidine-5-carboxylic acid with selenium dioxide was studied. It was observed that the 6-methyl group is oxidized to a hydroxymethyl, formyl, or carboxy group (in the latter case probably after dehydrogenation of ...
