[Reaction]

Biaryl bisphosphine ligand with narrow dihedral angle. The DTBM SEGPHOS ligand, as the ruthenium complex, gives superior enantioselectivity and diastereoselectivity through dynamic kinetic resolution in the asymmetric hydrogenation of a-substituted-β-ketoesters useful in the synthesis of carbapenum antibiotics.
