(R)-SEGPHOS is the enantiomeric form of (S)-SEGPHOS, delivering mirror-image enantioselectivity in ruthenium- and palladium-catalyzed asymmetric transformations. Its narrow bite angle design provides excellent stereocontrol.

Applications

  • Asymmetric hydrogenation of ketones
  • Enantioselective hydrogenation of β-keto esters
  • Asymmetric allylic alkylation
  • Pharmaceutical intermediate synthesis
