Axial Chirality Control by 2,4-Pentanediol for the Alternative Synthesis of C3*-TunePhos Chiral Diphosphine Ligands and Their Applications in Highly Enantioselective Ruthenium-Catalyzed Hydrogenation of ,-Keto Esters

Abstract A highly efficient strategy for the synthesis of a series of C3*-TunePhos chiral diphosphine ligands was well established with several remarkable features. The synthetic utility of these ligands was explored for the ruthenium-catalyzed asymmetric hydrogenation of ,-keto esters. Up to 99% ee values were achieved for the enantioselective synthesis of ,-hydroxy acid derivatives, which are very important chiral building blocks for the synthesis of a variety of natural products and biologically active molecules.

Die axiale Chiralitšt der abgebildeten Gold-Biphep-Komplexe wird durch ein chirales Anion wie (S)- 2 (=X*,) vorgegeben und bleibt auch nach der Abspaltung dieses Anions bestehen. Ein auf diese Weise erhaltener enantiomerenreiner Komplex katalysierte eine asymmetrische intramolekulare Hydroaminierung. [source]
