Application

Chiral Quest Phosphine Ligands for Asymmetric Hydrogenation

Ligand used in:
  • Redox-neutral domino reaction of arylethynylbenzylidenearylpentynones catalyzed by gold catalyst
  • Asymmetric allylic O-alkylation
  • Asymmetric alkylation of racemic secondary phosphines catalyzed by ruthenium chiral diphosphine hydride complexes
  • Stereoselective preparation of cyclopropylcarboxaldehydes via Rh-catalyzed asymmetric hydroformylation of cyclopropenes
  • Rhodium-catalyzed asymmetric hydrogenations
Provides comparable or superior enantioselectivities and catalytic abilities to BINAP in Ru-catalyzed asymmetric hydrogenations of β-keto esters, cyclic β-(acylamino)acrylates and α-phthalimide ketones.

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

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
