  • Exo- and diastereo- selective syntheses of himbacine analogs
    Publication number: 20060247450
    Abstract: This application discloses a novel process for the preparation of himbacine analogs useful as thrombin receptor antagonists. The process is based in part on the use of a base-promoted dynamic epimerization of a chiral nitro center.
    Type: Application
    Filed: January 12, 2006
    Publication date: November 2, 2006

  • Exo-selective synthesis of himbacine analogs
    Publication number: 20060217422
    Abstract: This application discloses a novel process for the synthesis of himbacine analogs, as well as the compounds produced thereby. The synthesis proceeds by alternative routes including the cyclic ketal amide route, the chiral carbamate amide route, and the chiral carbamate ester route. The compounds produced thereby are useful as thrombin receptor antagonists.
