Ring-chain tautomerism of 2-aryl-6-oxohexahydropyrimidine4-carboxylic acid sodium salts

It was shown by [sup.1]H and [sup.13]C NMR spectroscopy that the 2-aryl-6- oxohexahydropyrimidine-4-carboxylic acid sodium salts existed in [D.sub.2]O solution as a tautomeric mixture of cyclic and linear forms. The cyclic form consisted of two (2RS,4S)-stereoisomers, differing in the aryl substitue...

Description
Summary:It was shown by [sup.1]H and [sup.13]C NMR spectroscopy that the 2-aryl-6- oxohexahydropyrimidine-4-carboxylic acid sodium salts existed in [D.sub.2]O 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. Keywords: 2-aryl-6-oxohexahydropyrimidine-4-carboxylic acids, ring-chain tautomerism.
