The enantioselective total synthesis of the alkaloid aristoquinoline has been achieved in seven steps and 26% overall yield. A new preparation of the useful synthetic building block (–)-α-terpinyl amine was also developed in order to avoid stoichiometric mercury reagents or azide-containing intermediates. Key steps in the optimized synthetic route include an intramolecular nitrilium ion cyclization
The addition of perfluoroalkanoic acids to 3-carene involves opening of the cyclopropane ring at the peripheral bonds with formation of a mixture of isomeric p-menth-1-en-8-yl and m-menth-1-en-8-yl perfluoroalkanoates. The reaction rate decreases as the length of the perfluoroalkyl radical of the acid increases. Trichloroacetic acid reacted with 3-carene at a lower rate than does trifluoroacetic acid

It was shown that the acylhydroxysulfonium salt generated in situ from DMSO and trifluoroacetic anhydride causes low-temperature cyclization of geraniol, linalool, and nerol in an aprotic medium to a mixture of p-menthane monoterpenoids, and the maximum yield is obtained in the case of the last two terpenols. A similar result was obtained for E-nerolidol.
