The stereoisomerically pure esters of (2R,3S)-3-(4-hydroxy or 4-alkoxyphenyl)glycidic acid, which is a starting compound for the preparation of diltiazem, are prepared by stereospecific enzymatic hydrolysis. By using such an ester, it is possible to economically prepare the (2S,3S) isomer of diltiazem to the exclusion of other stereoisomers.
