Technical Notes:
1. Biaryl bisphosphine ligand with narrow dihedral angle. The DM-S EGPHOS® 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
3.Ruthenium catalyzed asymmetric hydrogenation of 3-quinuclidinone. See 44-0098 for Ru catalyst.
