Zusammenfassung:14,17 alpha -etheno- and ethanooestratrienes of the general formula I in which X is a -CH2-CH2- or bridge,   R is a hydrogen atom, a C1-C15-acyl, benzoyl, C1-C15-alkyl, C3-C9-cycloalkyl or alkylcycloalkyl group and   R is the group where R and R are, independently of one another, a hydrogen atom or a straight-chain or branched, optionally partially or completely fluorinated C1-C8-alkyl group, a process for the preparation thereof, pharmaceutical products containing these compounds, and the use thereof for producing pharmaceuticals, are described. The compounds have potent antioestrogenic activity.
