Desymmetrization of α-diimines: synthesis of new 3-(diaziridin-3-yl)oxaziridines

New heterocyclic compounds characterized by the presence of a diaziridine and an oxaziridine ring directly bound were reported. A first desymmetrization reaction of α-diimines using nosyloxycarbamate as aminating agent in a H2O/CH2Cl2 system gives (E)-3-(iminomethyl)diaziridine-1-carboxylates which were further functionalized obtaining the never synthesized before 3-(diaziridin-3-yl)oxaziridines.
