Abstract: Number of novel derivatives of dihydrotriazolo-and-tetrazolopyrimidines containing carboxamide group in position 6 were obtained by multicomponent Biginelli-type reaction. The structures of all synthesized compounds were proved by NMR and MS spectral methods. The method of three-component Biginelli-type reaction is well suited for the synthesis of new promising dihydroazolopyrimidines providing a scaffold for screening of biological activity.

Keywords: nitrogen heterocycles - dihydropyrimidines - multicomponent reactions - cyclocondensation
