摘要：
It was shown by 1H and 13C NMR spectroscopy that the 2-aryl-6-oxohexahydropyrimidine-4-carboxylic acid sodium salts existed in D2O solution as a tautomeric mixture of cyclic and linear forms. The cyclic form consisted of two (2RS,4S)-stereoisomers, differing in the aryl substituent configuration at the pyrimidine ring C-2 atom.
