A novel four-component reaction of alkoxyallenes with imines, iodine, and nitriles provided highly substituted imidazole derivatives in high overall yields. The simple three step protocol, exemplified by the reaction of methoxyallene ( 1) with imine 2, acetonitrile, and iodine leading to iodoethenyl imidazole 6 is presented with full experimental detail. Imidazole 6 could be further functionalized
