Questions And AnswerBack Directory
[Reaction]

  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 α-substituted-β-ketoesters. 
  2. Ruthenium catalyzed enantioselective synthesis of β amino acids by hydrogenation.
  3. Ruthenium catalyzed asymmetric hydrogenation of 3-quinuclidinone.
