Abstract
Method for obtaining the optical antipodes of the pantolactone characterized by the fact that pantolactone-dl with basic lithium compounds in aqueous solution or suspension or in a polar solvent, preferably a low alcohol, is transformed into lithium pantoate-dl and this compound in the presence of its polar solvent, preferably a low alcohol, is split into the optically active forms, the isolation of the desired isomers takes place according to the known crystallization process then the desired optically active form is transformed, in a known manner, in optically active pantolactone.
