MgII-Catalyzed Desymmetrization Reaction of meso-Aziridines with Hydroxylamines: Synthesis of Novel Chiral 1,2-Diamine Skeletons

A Mg-II-catalyzed desymmetrization reaction of meso-aziridines with hydroxylamines has been disclosed for the first time. A series of novel chiral 1,2-diamine skeletons were obtained in good yields and enantioselectivities. The reaction employed magnesium catalysis generated in situ from a simple oxazoline-OH chiral ligand. Obviously, the diverse structures of the obtained chiral 1,2-diamine compounds could allow them to be potential chiral ligands in future catalytic asymmetric synthesis studies.
