Description and 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
