    摘要: The invention relates to a novel process for the preparation of 17 .alpha.-hydroxy-20-oxopregnane derivatives of the general formula (I), ##STR1## wherein R.sub.1 means a hydroxy or an oxo group; andthe dotted lines optionally represent one or more additional valence bond(s), with the proviso that the dotted line in the 4-position and the dotted line in the 5-position cannot each simultaneously be an additional valence bond from steroids having 23,24-dinor-17(20)-dehydrocholan-22-oic -22-oic acid structure.According to the process of the invention a steroid derivative having 23,24-dinorcholan-22-oic acid structure, containing a double bond in 17(20)-position, is transformed to 17.alpha., 20-epoxy-23,24-dinorcholanoic acid, the latter is converted to a reactive acid derivative, which is then reacted with a salt-containing azide ion to yield a 17.alpha., 20-epoxy-23,24-dinorcholanoic acyl azide derivative and the azide obtained is reacted with a mineral or organic acid in an aqueous medium.

    摘要: The invention relates to new 16-amino-18,19,20-trinor-prostaglandin derivatives of general formula I, having at C-17 a substituted or unsubstituted phenyl group, wherein C-15 and C-16 may have either S or R configuration, Y stands for a hydrogen atom or a lower alkyl group, W stands for a hydrogen atom, halogen atom, hydroxy group, lower alkyl or alkoxy group, and their acid addition salts. These compounds can be prepared by removing the ester group and the p-nitrobenzyloxycarbonyl protective group of a 9.alpha.,11.alpha.,15-trihydroxy-16-p-nitrobenzyloxycarbonylamido-17-phenyl-5-cis,13-trans-18,19,20-trinor-prostadienoic acid derivative of general formula XII--wherein C-15 and C-16 may have either S or R configuration, W is as defined above, and Y stands for a lower alkyl group--in an optional sequence with the limitation that in those compounds of general formula I where W is as defined above and Y stands for a lower alkyl group, solely the p-nitrobenzyloxycarbonyl group is removed, and the resulting product of general formula I is optionally converted with an organic or inorganic acid into a salt.The new prostaglandin derivatives of the invention have valuable therapeutical properties, and can be applied in cattle raising for estrus and birth synchronization, furthermore in the veterinary praxis for the treatment of sterility, chronic endometritis and pyometry.
