IMINE-ENAMINE TAUTOMERISM IN DIHYDROAZOLOPYRIMIDINES. 2. SYNTHESIS AND TAUTOMERISM OF 1,4(3,4)-DIHYDROPYRIMIDOBENZIMIDAZOLES

Desenko, S. M.,Orlov, V. D.,Lipson, V. V.,Estrada, Kh.

, p. 976 - 980 (2007/10/02)

Cyclocondensation of 2-aminobenzimidazole with unsaturated ketones or the hydrochlorides of Mannich bases has yielded aromatic substituted 1,4(3,4)-dihydropyrimidobenzimidazoles.The dependence of the tautomer composition of the products on steric factors and on the electronic character of the substituents introduced has been studied.
