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

This is the authors' abstract. We don't add key points for this paper.

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.
