摘要

Stereospecific methods of synthesis of some cis-and trans-bicyclo [n. 3.0] alkane-1- carboxylic acids are described, specifically 5 a, 5 b, and 11. The cis ring fusion is insured by use of the Diels-Alder reaction, and the trans ring fusion is fixed by the necessity of a cis attachment of an intermediate five-membered cyclic lactamol to the existing cyclopentane ring in 9.
