alcohols gave the isomeric forms of the terpenes dill and epi-dillether, which were hydrogenated diastereoselectively to the corresponding (1R)- or (1S)-derivatives depending on the catalyst used. The oxidation of the latter ethers turned out to be stereoselective, affording either the corresponding p-menthan-9-oic lactone or the keto-acid derivatives depending on the starting isomer used.
