11BETA-HALOGEN-7ALPHA-SUBSTITUTED ESTRATRIENES, METOD FOR PRODUCING PHARMACEUTICAL PREPARATIONS CONTAINING SAID 11BETA-HALOGEN-7ALPHA- SUBSTITUTED ESTRATRIENES AND USE OF THE SAME FOR PRODUCING MEDICAMENTS
Metal-Free Visible Light Hydroperfluoroalkylation of Unactivated Alkenes Using Perfluoroalkyl Bromides
摘要:
Organic dye-catalyzed visible light induced hydroperfluoroalkylation of unactivated alkenes is described. Hydroperfluoroalkylation proceeds selectively and is applicable for various perfluoroalkyl bromide and alkenes including internal alkenes. The reaction mechanism is discussed, and it is shown that the hydrogen source varies with reaction conditions.

This invention describes the new 11&bgr;-halogen-7&agr;-substituted estratrienes of general formula I
in which
R11 is a fluorine or chlorine atom, and the other substituents have the meanings that are explained in more detail in the description.
The compounds have antiestrogenic properties or tissue-selective estrogenic properties and are suitable for the production of pharmaceutical agents.
