(57) [Summary] Formula (I) 1,2-isopropylideneglycerol enantiomers of formula (II) embedded image in the presence of cosolvents, catalyzed by free or immobilized lipase. A method for separating 1,2-isopropylideneglycerol benzoyl ester by a step comprising a step of partially and stereoselectively hydrolyzing an enzyme, wherein the hydrolysis is followed by crystallization to give a racemic form. (II) crystals, And selectively obtaining a mother liquor containing (II) in the form of a pure enantiomer. |
