WebFigure 7: The (R)-BINAP-Ru-(II)-catalyzed hydrogenation of acetol to (R)-1,2-propanediol is currently used for the industrial synthesis of antibacterial levofloxacin. The hydrogenation method is effective for converting β-keto carboxylic esters into β-hydroxy esters in high (up to 100%) enatiomeric purity. This entirely chemical approach WebSEGPHOS is a chiral ligand developed by Takasago that is used in asymmetric synthesis. [1] It was developed after BINAP and was investigated since it has a narrower dihedral angle between the aromatic faces. This was predicted and then confirmed to increase the enantioselectivity and activity of metal complexes of SEGPHOS.
