Rhodium(I)-Sulfonated-bdpp Catalysed Asymmetric Hydrogenation of Imines in Aqueous-Organic Two-phase Solvent Systems

Bakos, Jozsef,Orosz, Arpad,Heil, Balint,Laghmari, Mohamed,Lhoste, Paul,Sinou, Denis

, p. 1684 - 1685 (2007/10/02)

The imines ArC(Me)=NCH2Ph (Ar = Ph, 2-MeO-C6H4, 3-MeO-C6H4, 4-MeO-C6H4) are hydrogenated to the corresponding amines with extremely high enantioselectivities up to 96percent under very mild conditions, using rhodium complexes associated with sulfonated bdpp.
