Application

Atropisomeric MeOBIPHEP ligands

• Hydrogenation of α- and β-functionalized ketones
• Hydrogenation of heteroarenes
• C–C coupling reactions

Atropisomeric diphosphine; the Rh(I) complex is employed for highly enantioselective asymmetric isomerization of allylamines to enamines; the Ru(II) complex hydrogenates ß-keto esters in high enantioselectivity; the Pd(0) complex for cyclization of hydroxy allylic carbonates.

Ligand for ruthenium-catalyzed greener amine synthesis by enamine reduction with hydrogen gas.

Asymmetric Synthesis of (S)-3-Amino-4-methoxy-butan-1-ol by Way of Reductive Amination
