A highly efficient molecular iodine mediated multicomponent reactions leading to 1,2,5-trisubstituted imidazoles from methyl ketones,anilines,and amino source（ammonium acetate,ammonium formate or tosylmethylisocyanide）was developed（Figure 1）.This protocol was envisioned that the substrate 1 could be divided into two sequences;and the corresponding intermediates B and 1’’could finally r...
