(1S,1S',2R,2R')-(+)-1,1'-DI-T-BUTYL-[2,2']-DIPHOSPHOLANE Usage And Synthesis

Uses

Chiral Quest Phosphine Ligands for Asymmetric Hydrogenation

Catalytic ligand used in:

  • Preparation of α-borono-substituted alkylarenes by asymmetric hydroboration of styrenes catalyzed by copper(I)
  • Enantioselective synthesis of spiroindane di-Me acetic acid via hydrogenation of spiroindane di-Me acetic acid catalyzed by Ru(II)
  • Asymmetric γ-addition of thiols to allenoates
  • 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
