BICYCLOALKANE DERIVATIVES |
| 摘要 |
<p>A bicycloalkane derivative of the general formula Ia (Ia) which are useful for the preparation of intermediates for the total synthesis of steroids, are produced by hydrogenating a compound of the general formula II (II) in the presence of a palladium-carbon catalyst and a lower alcohol or ketone. In the above formulae n is the integer 1 or 2; R1 is a lower alkyl group; R2 18 an alkyl, aryl or aralkyl group; and X is a free or ketalized carbonyl group or a free, esterified or etherified hydroxymethylene group.</p> |
