摘要:
A process for preparing bromine- or iodine-unlabeled or radioactively labeled 17.alpha.-bromoethynyl- and 17.alpha.-iodoethynyl-17.beta.-hydroxy steroids of the androstane and estrane series of the partial formula ##STR1## wherein is a single bond or a double bond,V is a carbon-carbon bond or a methylene group,R is hydrogen or methyl, andX is bromine or iodine,from corresponding 17.alpha.-ethynyl-17.beta.-hydroxy steroids, comprises treating the starting steroid in an inert solvent with a brominating agent or an iodinating agent in the presence of a silver salt.The process enables production of old and new compounds having value as pharmacologically active compounds and also as diagnostic agents when the iodine or bromine is radioactive.
