Application

Chiral Quest Phosphine Ligands for Asymmetric Hydrogenation

Reactant for:
  • Asymmetric hydrogenation of ketones with TunePhos/diamine/ruthenium complexes
  • Stereoselective preparation of arylalkyl esters via enantioselective hydrogenation of enol acetates

Precatalyst for:
  • Enantioselective iridium-catalyzed carbonyl allylation from alcohol or aldehyde by transfer hydrogenative coupling of allyl acetate

Catalyst for:
  • Enantioselective hydrogenation of a-keto esters to a-hydroxy esters using Ru-tunephos catalysts
Provides comparable or superior enantioselectivities and catalytic abilities to BINAP in Ru-catalyzed asymmetric hydrogenations of β-keto esters, cyclic β-(acylamino)acrylates and a-phthalimide ketones.

Hydrogenation of a series of cyclic beta-(acylamino)acrylates with tetrasubstituted olefins has been accomplished successfully with the use of Ru catalysts with chiral biaryl ligands such as C3-TunaPhos, and up to over 99% ee's have been achieved. This methodology provides an

A new type of alpha-phthalimide ketones was hydrogenated in excellent enantioselectivity by using a Ru-(C3-TunePhos) complex as the catalyst. Up to 10 000 turnovers have been achieved in more than 99% ee in the hydrogenation reaction. A dynamic kinetic resolution
