(1R,1'R,2S,2'S)-DUANPHOS Chemical Properties,Uses,Production

Reactions

  1. As a highly electron-donating and conformationally rigid ligand, the rhodium complex of DuanPhos has exhibited remarkably high enantioselectivities and reactivities for the hydrogenation of a variety of functionalized olefins.
  2. Rhodium/DUANPHOS catalyst used in the synthesis of 2-trifluoromethyl lactic acid by asymmetric hydroformylation.
Reactions of 528814-26-8

Uses

Chiral Quest Phosphine Ligands for Asymmetric Hydrogenation

Catalytic ligand used for:

  • Stereoselective synthesis of cyano-substituted dihydropyrroles by annulation of cyanoallenes
  • Rhodium-catalyzed intermolecular enantioselective hydroacylation of alkynes to give alpha- and beta-substituted unsaturated ketones by kinetic resolution
  • Stereoselective preparation of β-amino nitriles via rhodium-catalyzed asymmetric hydrogenation of amino acrylonitriles
  • Stereoselective preparation of anti-1,3-amino alcohols via rhodium-catalyzed asymmetric hydrogenation of β-ketoenamide intermediates
  • Stereoselective preparation of acetylaminoindane via rhodium-catalyzed asymmetric hydrogenation of acetylaminoindene

General Description

(1R,1′R,2S,2′S)-DuanPhos is an electron-rich chiral phosphine ligand mainly for transition metal catalyzed asymmetric hydrogenation.
