Abstract: A process for resolving racemic alpha -hydroxy- beta , beta -dimethyl- gamma -butyrolactone, referred to as D,L-pantolactone, into its optical antipodes, based on the separation of diastereomeric salts of D,L-pantoic acid ( alpha , gamma -dihydroxy- beta , beta -dimethylbutyric acid), produced from D,L-pantolactone, by means of (-)-3-aminomethylpinane, (+)-3-aminomethylpinane or one of their acid addition salts, as a new resolving agent.
