Abstract

L'invention est relative à de nouveaux diastéréomères de formule (I). Ils sont préparés en éliminant le groupe éthylène-cétal d'un composé de formule générale (III) (où R1 est un atome d'hydrogène, ou un groupe amido-protecteur constitué par un radical phényle ou benzyle éventuellement substitué par un ou plusieurs groupes méthoxy), et en réduisant le nouveau composé ainsi obtenu, puis en isolant de formule générale I obtenu, et, si cela est désiré, en séparant la paire de diastéromères obtenue en ses composants.
