A novel CuI/BF3 center dot Et2O/O-2-mediated reaction utilizing ketones and benzylamines for the construction of substituted imidazoles in one step under mild conditions has been demonstrated. This protocol involved the removal of eight hydrogen atoms, the functionalization of four C(sp(3))-H bonds and three new C-N bond formations.
