Versuchsvorschrift

The reaction times are suitably 1 to 1000 hours, preferably 1 to 200 hours. Namely, the reaction time depends on the kind of the racemic esters of 3-hydroxy hexanoic acid which are starting materials. The conversion of 20-80% is attained within the above preferable reaction times. In this case, in the reaction of the conversion of 50% or less, (R)-3-hydroxyhexanoic acid having optical purity over 90% ee is obtained, while in the reaction of the conversion of 50% or more, (S)-3-hydroxyhexanoic acid having optical purity over 90% ee is obtained.
