Iron(iii)/quinoxaline-derived N,N-ligand catalyzed oxygen transfer reaction of N-vinyl nitrones through selective 4π-electrocyclization and N–O bond cleavage

Abstract

We describe an iron(iii)/quinoxaline-derived N,N-ligand promoted O-transfer reaction of N-vinyl nitrones through selective O-4π-electrocyclization and N–O bond cleavage to prepare a variety of 2,5-dihydrooxazoles in good yields.
