Abstract

New and Rapid Access to Synthesis of Novel Polysubstituted Imidazoles Using Antimony Trichloride and Stannous Chloride Dihydrate as Effective and Reusable Catalysts. -A new and efficient and environmentally benign synthesis of the title compounds (IV),(VI) by multicomponent reaction of various aldehydes, benzil, aliphatic and aromatic primary amines and ammonium acetate under solvent--free conditions is presented. The reaction is completed within short reaction times with both catalysts whereas, somewhat better yields are mostly achieved with SbCl 3 . The catalysts can be easily recovered and reused up to five times without significant loss of activity. -(POORALI, L.; KARAMI*, B.; ESKANDARI, K.; AZIZI, M.; J. Chem. Sci.
