METHOD FOR THE ENANTIOSELECTIVE PRODUCTION OF OPTICALLY ACTIVE 4-HYDROXY-2,6,6-TRIMETHYL-CYCLOHEX-2-ENONE DERIVATIVES
摘要:
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).
