A straightforward cross-dehydrogenativecouplingapproach to incorporate alicyclic amino residues into the structure of model cyclic aldonitrones, 2H-imidazole oxides, is reported. The elaborated C(sp2)–H functionalization is achieved by employing cyclic amines in the presence of the I2–tert-butyl hydroperoxide (TBHP) reagent system. As a result, a series of 19 novel heterocyclic derivatives were obtained
