Abstract:

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

Keywords: Copper catalyzed reaction, nitroolefin, amidine, [3+2] cycloaddition, imidazole derivatives.
