Diacetato{(R)-(+)-5,5'-bis[di(3,5-xylyl)phosphino]-4,4'-bi-1,3-benzodioxole}ruthenium(II) Ru(OAc)2[(R)-dm-segphos]　 Chemical Properties,Uses,Production

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.
Reactions of 944450-50-4

Uses

(S)-Ru(OAc)2(DM-SEGPHOS?) can be used as a catalyst in:

  • The enantioselective asymmetric hydrogenation reaction.
  • The asymmetric reductive amination reaction.
  • The total synthesis of (-)-tubingensin B via Suzuki-Miyaura coupling and aryne cyclization reactions.
