    摘要: 17.alpha.-bromo-.alpha. and 17.alpha.-iodo-vinyl-estrane derivatives of general formula I ##STR1## wherein X is a bromine or iodine atom in Z or E position,R.sup.1 is hydrogen, hydroxy or acyloxy with up to 3 C atoms,R.sup.2 is hydrogen, alkyl with up to 3 C atoms and alkanoyl and aroyl with up to 7 C atoms,R.sup.3 is hydrogen or methyl,R.sup.4 is a hydrogen atom in the .alpha. or .beta. position,R.sup.5 is hydrogen, methyl or methoxy andR.sup.6 is hydrogen or methyl,are pharmacologically effective with a profile of action like ethinylestradiol and in the form of their radioactively labeled compounds are also valuable diagnostic media.The Z-isomers can be prepared by a new process by reaction of the corresponding 17.alpha.-ethinyl steroids with trialkyl (or phenyl) tin hydride with addition of a free radical former.

    摘要: Competitive progesterone antagonists, including two novel steroids, viz., 11&bgr;,19-[4-(cyanophenyl)-o-phenylene]-17&bgr;-hydroxy-17&agr;-(3-hydroxyprop-1(Z)-enyl)-4-androsten-3-one and 11&bgr;,19-[4-(3-pyridinyl)-o-phenylene]-17&bgr;-hydroxy-17&agr;-(3-hydroxyprop-1(Z)-enyl)-4-androsten-3-one, inhibit formation of endometrial glands at below their ovulation inhibiting dose and the abortive dose, and thus achieve oral contraception in females without adversely affecting the menstrual cycle and without risk of aborting a previous implanted fertilized egg or a fetus.
