Facile Synthesis of Polysubstituted Imidazoles through CBr4‐Mediated Tandem Cyclization of Amidines with 1,3‐Dicarbonyl Compounds or Ketones

Polysubstituted imidazoles were synthesized in a facile metal‐free CBr 4 ‐mediated tandem cyclization of amidine with 1,3‐dicarbonyl compounds or ketones. The desired products were obtained in moderate to good yields by using simple operation techniques and mild conditions.
