Abstract
2-Alkylmercapto-4-hydroxy-3,4,5,6-tetrahydro- and 2-alkylmercapto-3,6-dihydropyrimidines were synthesized by the reaction of substituted 4-hydroxyhexahydro- and 1,2,3,6-tetrahydropyrimidine-2-thiones with alkyl halides. It is shown that the nucleophilic center in the alkylation is the sulfur atom. The capacity of the synthesized compounds for prototropic ring-chain tautomerism was established.
