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-substituted-ß-ketoesters. See 15-0066 2. Ruthenium catalyzed enantioselective synthesis of ß amino acids by hydrogenation. References: 1. US. Pat 7626034 |
