Starting from (+)-3-carene 1, naturally occurring bicyclic, monoterpene hydrocarbon, (-)-cis- carane-4-one 3 was obtained as a result of the two-step synthesis. Our investigations were focused on the optimization of chemical Baeyer-Villiger reaction of 3 leading to a-lactones. A mixture of terpenoid lactones 4a, 4b was obtained and next separated using column chromatography. The pure compounds were subjected to the evaluation of antifeedant activity towards three species of storage insects. Fusarium culmorum, Fusarium oxysporum and Aspergillus niger were chosen among six fungal strains to perform microbiological Baeyer- Villiger oxidation. As a result, three derivatives were isolated and characterized by spectroscopic methods. ARKAT-USA, Inc.
Reactions of cis-and trans-epoxy derivatives of (+)-3-carene and limonene with aldehydes over askanite-bentonite clay

cis-and trans-Epoxy derivatives of (+)-3-carene, limonene, and dipentene react with aldehydes in the presence of askanite-bentonite clay to give acetals. Hydrolysis of the latter selectively yields the corresponding cis-diols. The relative contribution of intra-and intermolecular processes in the reactions of epoxy derivatives with aldehydes is determined mainly by steric factor. * This study was financially supported by the Russian Foundation for Basic Research (project no. 97-03-32 952a).
Catalytic transformations of 3-carene oxide over alumina-rare earth oxide catalysts

Isomerization of 3-carene oxide over binary oxide catalysts like Al2O3-Y2O3, Al2O3-Sm2O3, Al2O3-Eu2O3, Al2O3-Pr6O11 and Al2O3-Nd2O3 at 80 deg C and 110 deg C has been studied. 3,6,6-Trimethylbicyclohexane-3-carboxaldehyde and caranone are the major products formed at 80 deg C.Rise in reaction temperature results in an increase in epoxide transformation and an irregular variation in the yield of products.
