  • Asymmetric catalytic hydrogenation process for preparation of chiral cyclic &bgr;-aminoesters
    Patent number: 6835841
    Abstract: A novel process for the asymmetric synthesis of substituted cyclic &bgr;-amino-carboxylates of the type shown in the specification from appropriate &bgr;-enamino-ester starting materials is described. These compounds are useful as intermediates for MMP and TACE inhibitors.
    Type: Grant
    Filed: September 11, 2003
    Date of Patent: December 28, 2004
