A process for producing (6R)-2,2,6-trimethylcyclohexane-1,4-dione (levodione) involves contacting 2,6,6-trimethyl-2-cyclohexene-1,4-dione with at least one kind of yeast capable of converting 2,6,6-trimethyl-2-cyclohexene-1,4-dione into (6R)- 2,2,6- trimethyl-cyclohexane-1,4-dione and selected from the group of species consisting of Saccharomyces rouxii (Zygosaccharomyces rouxii), Saccharomyces delbrueckii (Saccharomyces unisporus, Torulaspora delbrueckii), Saccharomyces willianus, Zygosaccharomyces bailii and Candida tropicalis, and functional equivalents, subcultures, mutants and variants of such species, in water, a water-miscible organic solvent or a mixture of water and said water-miscible organic solvent containing at least one assimilable carbon source, followed by isolating the resulting (6R)-2,2,6- trimethylcyclohexane-1,4-dione from the reaction medium after completion of the reaction. Levodione is a useful intermediate for the production of carotenoids, particularly (3R,3'R)-zeaxanthin.
