    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.

    摘要: Bicycloalkane derivatives of the formula ##STR1## wherein n is 1 or 2, R.sub.1 is lower alkyl, Acyl is alkanoyl, and Y is --S--R.sub.2, --SO.sub.m --R.sub.2, or ##STR2## wherein m is 1 or 2, R.sub.2 is alkyl, R.sub.3 is hydrogen or lower alkyl, R.sub.4 is acyl or phenyl optionally substituted with lower alkoxy, benzyloxy or alkanoyloxy; and Z is nitro, lower alkoxycarbonyl, lower alkanoyl, lower alkylsulfinyl, or lower alkylsulfonyl are useful intermediates in the total synthesis of steroids. The compounds are prepared by reacting a corresponding compound lacking the CH.sub.2 Y substituent with formaldehyde and a mercaptan or sulfinic acid, followed if desired by oxidation and optional salt condensation.
