Description

  • General description: (1R,1′R,2S,2′S)-DuanPhos is an electron-rich chiral phosphine ligand mainly for transition metal catalyzed asymmetric hydrogenation.
  • Application: Chiral Quest Phosphine Ligands for Asymmetric HydrogenationCatalytic ligand used for:Stereoselective synthesis of cyano-substituted dihydropyrroles by annulation of cyanoallenesRhodium-catalyzed intermolecular enantioselective hydroacylation of alkynes to give alpha- and beta-substituted unsaturated ketones by kinetic resolutionStereoselective preparation of β-amino nitriles via rhodium-catalyzed asymmetric hydrogenation of amino acrylonitrilesStereoselective preparation of anti-1,3-amino alcohols via rhodium-catalyzed asymmetric hydrogenation of β-ketoenamide intermediatesStereoselective preparation of acetylaminoindane via rhodium-catalyzed asymmetric hydrogenation of acetylaminoindene
