Synthesis of Novel Tetrahydropyrimidines via the Reaction of Sodium [1-(3,3-Diethoxypropyl)ureido]methanesulfonates with C-Nucleophiles.

A series of new substituted tetrahydropyrimidines was obtained by the reaction of sodium [1-(3,3-diethoxypropyl)ureido]methanesulfonates with various C-nucleophiles (4-chlororesorcinol, sesamol, 2,4-dihydroxybenzoic acid, 4-hydroxy-6-methyl-2H-pyran-2-one) in chloroform in the presence of trifluoroacetic acid.
