(1R,1'R,2S,2'S)-DUANPHOS Usage And Synthesis
Reactions
- 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.
- Rhodium/DUANPHOS catalyst used in the synthesis of 2-trifluoromethyl lactic acid by asymmetric hydroformylation.
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.
