Regio‐ and Stereoselective Iron‐Catalyzed Oxyazidation of Enamides Using a Hypervalent Iodine Reagent
Résumé
Abstract A novel regio‐ and diastereoselective iron‐catalyzed intermolecular oxyazidation of enamides using various azidobenziodoxolone (ABX) derivatives is presented. A variety of α‐N 3 amino derivatives and of α‐N 3 piperidines were synthesized in good yields and under mild reaction conditions. The reaction involves a radical process using cheap FeCl 2 as the initiator.
