Technical Notes:
1. 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 a-sub stituted-ß-ketoesters. See 15-0066.
2. Ruthenium catalyzed enantioselective synthesis of ß amino acids by hydrogenation.
