Dimethylammonium dichlorotri(chloro)bis{(R)-(+)-5,5'-bis[di(3,5-xylyl)phosphino]-4,4'-bi-1,3-benzodioxole}diruthenate(II) [NH2Me2][{RuCl((R)-dm-segphos)}2(Cl)3] Usage And Synthesis

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.

Uses

(R)-[(RuCl(DM-SEGPHOS?)2(μ-Cl)3][NH2Me2] can be used as a catalyst for the asymmetric hydrogenation of ketones to chiral alcohols. It can also be utilized to prepare (R)-methyl-3-hydroxybutanoate from methyl acetoacetate via stereoselective hydrogenation reaction.
