The 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. The chemistry taught herein can be exemplified by the following. (I)
L'invention concerne un procédé de préparation d'analogues de l'himbacine utiles comme antagonistes des récepteurs de la thrombine. Le procédé est fondé partiellement sur l'utilisation d'une épimérisation dynamique à promotion basique d'un centre nitro chiral. La chimie définie dans la description peut être exemplifiée par celui-ci.
