Oxidation of some derivatives of tetrahydropyrimidine-5-carboxylic acid with selenium dioxide
Khanina,Dubur
, p. 412 - 414 (2007/10/02)
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
