Abstract: Pyrimidine derivatives of the formula I ##STR1## in which R.sup.1, R.sup.2, X and Y have the stated meaning, the salts thereof and a process for the preparation thereof are described. Because of their sorbitol-accumulating activity, they are suitable for use as reagents for an advantageous pharmacological screening model for testing aldose reductase inhibitors.

Abstract: Disclosed are novel 14,17.alpha.-etheno- and -ethanoestratrienes according to general Formula I ##STR1## wherein X is a --CH.sub.2 --CH.sub.2 or ##STR2## R.sup.1 is a hydrogen atom, a C.sub.1 - to C.sub.15 -acyl, benzoyl, C.sub.1 - to C.sub.15 -alkyl, C.sub.3 - to C.sub.9 -cycloalkyl or alkylcycloalkyl group, andR.sup.2 is the grouping ##STR3## wherein R.sup.3 and R.sup.4 independently of each other mean a hydrogen atom or a straight-chain or branched, optionally partially or completely fluorinated C.sub.1 -C.sub.8 -alkyl group,a process for their preparation, pharmaceutical preparations containing these compounds, as well as their use for the production of medicinal agents.The novel compounds exhibit strong antiestrogenic efficacy.
