摘要：

The known epimeric cis-bicyclo[3.3.0]octan-2-ols have been stereochemically related to the two epimeric cis-bicyclo [3.3.0]-octane-2-carboxylic acids. This has been achieved by the perbenzoic acid cleavage of the two methyl ketones prepared from the two acids, forming the corresponding alcohols. Absolute configurations have been assigned to these compounds on the basis of these transformations and mechanistic considerations.
