Technical Notes:
1. Biaryl bisphosphine ligand with narrow dihedral angle. The DM-S EGPHOS ligand, as the ruthenium complex, gives superior
ena ntioselectivity and dias te re oselectivity in the asymmetric hydrogenation of a-subs tituted- ß-ke toesters. See 1 5-0066
2.Ruthenium catalyzed enantioselective synthesis of ß amino acids by hyd rogenation
3.Ruthenium catalyzed asymmetric hydrogenation of 3 quinuclidinone. See 44-0098 for Ru catalyst.
