[摘要]:The design and synthesis of a C-2-symmetric chiral 1,2-bis(diphenylphosphino)benzene ligand via the rhodium-catalyzed intramolecular [2+2+2] cycloaddition followed by reduction are disclosed. This new chiral dppbz-type ligand could be employed for the rhodium-catalyzed asymmetric alkene hydrogenation. |
