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	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. Ruthenium catalyzed enantioselective synthesis of β amino acids by hydrogenation. 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.
