ABSTRACT:
The present invention provides optically active compounds and a process for producing the optically active compounds by a biochemical method in which specific compounds having hydroxyl or acyloxy groups are reacted with esters in the presence of hydrolase. The compounds have the following general formula: ##STR1## wherein R.sup.1, R.sup.2 and R.sup.3 are selected from alkyl groups having 1-4 carbon atoms and phenyl groups, X is selected from a hydrogen atom and ##STR2## R is selected from alkyl groups having 1-20 carbon atoms, and C* indicates an asymmetric carbon atom.
