摘要
The multicomponent reaction of acetophenone derivatives with heterocyclic amines and benzaldehyde derivatives in water in the presence of H-ferrierite zeolite for short time 8-15 min afforded new series of [1,2,4]triazolo[1,5-a]pyrimidines and pyrimido[1,2-a]benzimidazole derivatives. The structure of the actual tutomeric product was established on the bases of spectral data [IR, NMR (H-1 and C-13), and nuclear Overhauser effect] and density functional theory calculations.
