An efficient four component one pot synthesis of tetra substituted imidazoles using SnCl۴/γ-Al۲O۳ nano particles as a green catalyst under thermal condition

چکیده مقاله

Nowadays, the application of nano particles as catalysts are developed because of their highly catalyctic activities. In continuation of our interest in the application of new solid acid catalysts in organic synthesis via MCRs, herein, we represent an efficient synthesis of 1,2,4,5-tetra substituted imidazole derivatives via a green one pot four component reaction using nano γ-Al2O3/SnCl4 as a solid acid catalyst under thermal and solvent free conditions.
