RACEMIZATION OF OPTICALLY ACTIVE ALPHA-2,2-(DIMETHYLAMINO) ETHYL-2- THIOPHENEMETHANOL

摘要

The present invention discloses racemization of unwanted enantiomer of the compound of formula (I) or its salts by subjecting the enantiomerically enriched chemical mixture to sequential oxidation and reduction reactions. The invention further discloses a process for recovery of enantiomers from racemic mixtures containing stereoisomers of compounds having the general formula (I) or it's salt.
