An intra-intermolecular iron-catalyzed aminoazidation of non-activated alkenes is reported for the preparation of imidazolidinone, oxazolidinone, and pyrrolidinone derivatives. The method uses cheap and abundant iron as a catalyst and commercially available TMSN3 as an azide source. This domino process allows, in a single operating step, for a ring-closure that generates an aza-heterocycle and the introduction of an azido appendage tethered to the heterocycle. The conditions developed offer a sustainable alternative method for the preparation of unsymmetrical vicinal diamine compounds.
