The present invention relates to a process for enantioselectively preparing optically active 4-hydroxy-2,6,6-trimethylcyclohex-2-en-1-one derivatives of the formulae (I) or (Ia) and to a process for preparing (3S,3′S)-astaxanthin of the formula (III), comprising the process for preparing the compound of the formula (I).
A method used for synthesizing intermediates for use in the synthesis of carotenoids and carotenoid analogs, and/or carotenoid derivatives. In some embodiments, the invention includes methods for synthesizing optically active intermediates useful for the synthesis of optically active carotenoids. Synthesis of optically active carotenoids, in one embodiment, may be accomplished by forming an optically active dihydroxy intermediate from ketoisopherone. The optically active dihydroxy intermediate may be converted into optically active zeaxanthin.
