  • C1-Symmetric Bisphospine Ligands and Their Use in the Asymmetric Synthesis of Pregabalin
    Publication number: 20090124820
    Abstract: Materials and Methods for preparing (S)-(+)-3-(aminomethyl)-5-methyl-hexanoic acid and structurally related compounds via enantioselective hydrogenation of prochiral olefins are disclosed. The methods employ novel chiral catalysts, which include C1-symmetric bisphosphine ligands bound to transition metals.
    Type: Application
    Filed: January 14, 2009
    Publication date: May 14, 2009
