Usage

Reaction

Biaryl bisphosphine ligand with narrow dihedral angle. The DM-SEGPHOS ligand, as the ruthenium complex, gives superior enantioselectivity and diastereoselectivity in the asymmetric hydrogenation of α-substituted-β-ketoesters. Ruthenium catalyzed enantioselective synthesis of β amino acids by hydrogenation. Ruthenium catalyzed asymmetric hydrogenation of 3-quinuclidinone.
