    Topics: Chemistry and Pharmacology
    Description / Table of Contents: A series of 6-β substituted derivatives of α and β 3-fluoro 17β-hydroxy (or acetoxy)-5(10) estrene were studied by mass spectrography. The influence of the substitution as also the stereochemistry of fluorine were discussed.
    Notes: Une série de dérivés substitués en 6β des fluoro-3α et β hydroxy ou acétoxy-17β estrénes-5(10) a été étudiée par spéctrographie de masse. L'influence de la substitution ainsi que la stéréochimie du fluor ont été discutées.

    Etude de Steroides Fluores par Spectrometrie de Masse - IV. Fluoro-3 Epoxy-5,6 Steroides (1973)

    Topics: Chemistry and Pharmacology
    Description / Table of Contents: Studies of 5,6 epoxy steroids fluorinated on carbon in position 3 do not permit the influence of the fluorine atom on the fragmentation to be clearly stated. On the other hand, it is shown that the stereochemistry of the epoxide plays a prominent part in the fragmentation.
    Notes: L'étude d'époxydes 5,6 de stéroïdes flourés en 3 ne nous a pas permis de mettre en évidence l'influence de l'atome de flour sur la fragmentation. Par contre, nous avons montré que la stéréochimie de l'époxyde joue un rôle prépondérant.
