摘要: trans-Fused octahydroisoindole-1-carboxylic acids are bicyclic proline analogues of potential interest in the search for new drugs. Within this work, the trans-fused octahydroisoindole system has been constructed using methyl trans-2-(hydroxymethyl) cyclohexane-1-carboxylate as the key synthetic precursor, in turn readily prepared from inexpensive cis-cyclohexane-1,2-dicarboxylic anhydride. Both the (1S*, 3aR*, 7aR*)- and the (1R*, 3aR*, 7aR*)-octahydroisoindole-1-carboxylic acids were prepared through the Strecker reaction of methyl trans-2-formylcyclohexane-1-carboxylate as the key step. Finally, (1S*, 3aR*, 7aR*)-octahydroisoindole-1-carboxylic acid was obtained with good yields in a highly stereoselective manner using (3aR*, 7aR*)-octahydroisoindole-1-one as a suitable scaffold.
