摘要：A ries of 2,4,5-trisubstituted-imidazoles has been synthesized with good to excellent yields by
the one-pot condensation reaction of 1,2-dicarbonyl compounds, benzaldehydes, and ammonium acetate in the prence of 4 molecular sieves modified with titanium(IV) as an efficient heterogeneous catalyst. The catalyst could be recovered easily and reud without significant loss of activity.
