Racemic modifications of optically active amines are treated with (-)-di-O-isopropylidene-2-keto-L-gulonic -keto-L-gulonic acid to form diastereomeric salts. The so-formed diastereomeric salts are separated and chemically decomposed to give the desired enantiomers of the amine. The resolving agent, (-)-di-Oisopropylidene-2-keto-L-gulonic acid, is recovered by precipitation from aqueous solution. |
