was shown for the first time that dihydrocarvone can be selectively produced by gold-catalyzed one pot transformation of carvone oxime. This reaction was carried out at 100 degrees C under hydrogen pressure of 9 bar over 1.9 wt.% Au/TiO2 catalyst using methanol as a solvent. Dihydrocarvone synthesis was shown to occur via carvone formation with the subsequent hydrogenation of its conjugated C=C double bond. Application of Au/TiO2 catalyst for both deoximation and selective hydrogenation of olefinic C=C functional group is reported for the first time. The combination of these steps provides optimization of the synthetic method for dihydrocarvone production from carvone oxime which is a key intermediate in carvone synthesis from limonene. Despite a lower reaction rate than in the case of carvone, a significant increase in the stereoselectivity towards trans-dihydrocarvone was observed in the case of carvone oxime hydrogenation. The ratio between trans- and cis-dihydrocarvone was close to 4.0 compared to 1.8 achieved in the case of carvone hydrogenation. (C) 2016 Elsevier B.V. All rights reserved.
