ABSTRACT:
Racemic modifications of optically active primary or tertiary amines are treated with lasalocid to form diastereomeric salts. The so-formed diastereomeric salts are separated and, subsequently, can be chemically decomposed to give the desired enantiomers of the amine. The resolving agent, lasalocid, is recovered in this process by precipitation or evaporation from organic solvents.
