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.
