چکیده

al-mcm-41 nanoreactors is found to be a remarkable efficient catalyst for one-pot multicomponent cyclocondensation of benzil, aniline or ammonium acetate and aromatic aldehydes for the synthesis of polysubstituted imidazoles under solvent-free conditions. the reaction was efficiently promoted by 10 mg nano-al-mcm-41 and the heterogeneous catalyst was recycled for four runs in this reaction without losing its catalytic activity. the key advantages of this process are operational simplicity, reusable catalyst, shorter reaction time, convenient work-up procedures, avoiding the use of organic solvents and purification of products by non-chromatographic methods. by this advantage, several polysubstituted imidazoles as pharmaceutical important molecules can be prepared in high yield and high purity.

One-Pot solvent-free synthesis of Highly Substituted Imidazoles catalyzed by zeolite

A series of tri- and tetra- substituted imidazoles were synthesized from benzyl, aldehyde and ammonium acetate in the presence of zeolite as an ecofriendly reusable catalyst under microwave irradiation in the absence of solvent. The yields are high to excellent and the use of microwave irradiation reduces reaction times to few minute.
