ed C(sp3)–H azidation was a keystep for the cycloaminative process. An unprecedented method for metal-free dehydrogenative N-incorporation into C(sp3)–H and C(sp2)–H bonds for the synthesis of diverse imidazoles has been disclosed. The overall transformation involves the construction of four C–N bonds through hydroamination-azidation-cyclization sequence. The reaction can be easily handled and proceeds
