Abstract
A method for preparing nootkatone, nootkatol or mixtures thereof by oxidizing valencene, wherein the valencene is exposed to an oxygenated atmosphere in a suitable reaction medium and in the presence of an unsaturated fatty acid hydroperoxide, and the nootkatone and/or nootkatol is (are) optionally separated from the reaction medium. The method enables nootkatone yields of around 60 g per kg of reaction medium to be achieved.
