SYNTHESIS OF 1-SUBSTITUTED DIHYDROPYRIMIDINONE AND QUINAZOLINONE DERIVATIVES

Mitskyavichyus, V. Yu.,Baltrushis, R. S.

, p. 1185 - 1188 (2007/10/02)

Condensation of N-substituted β-alanines (synthesized from anthranilic acid or its esters and acrylic acid) with urea afforded the corresponding 1-substituted dihydropyrimidinedione and quinazolinedione.When potassium thiocyanate was employed in the reaction instead of urea, decarboxylation and desulfuration occurred.
