A simple and facile approach to highly functionalized imidazoles in moderate to good yields was developed. This method involves Cu-catalyzed aerobic [3+2] cycloaddition of amidines with nitro olefins in absence of ligand. Based on observation of the intermediates, possible reaction mechanism different from the same reported approach was proposed.
