Bicycloalkane derivatives of the formula STR1 WHEREIN N IS 1 OR 2, R1 is lower alkyl, X is carbonyl or free or etherified hydroxymethylene, and Y is --S--R2, --SOm --R2, or STR2 wherein m is 1 or 2, R2/sub

Process for the preparation of bicycloalkane derivatives

Bicycloalkanes useful as intermediates in the total synthesis of steroids of the formula STR1 WHEREIN N IS THE INTEGER 1 OR 2; R1 is lower-alkyl; X is free or ketalized carbonyl or free, esterified or etherified hydroxymethylene; and Y is --SO2 --R2 or --C(Z)(R3)--R4 wherein R2 is alkyl, aryl or aralkyl R3 is H or lower-alkyl, R4 is alkoxycarbonyl or acyl and Z is lower-alkoxycarbonyl, lower acyl, lower alkylsulfinyl or lower-alkylsulfonyl, are produced by the steps of hydrogenating a compound of the formula STR2 AND CONDENSING THE THUS-PRODUCED RING SATURATED COMPOUND WITH A SALT OF THE FORMULA C(Z)(R3)R4 -Me+ wherein n, X, R1, R2, R3, R4 and Z have the values given above.
