1-Menthol can be readily obtained from racemic menthol by conversion of the latter to the diastereomeric esters of an optically active amino acid and chromatographing the diastereomers. The separation of the diastereomeric esters is relatively insensitive to the support or to the solvent used as eluant, and satisfactory separation occurs under a broad variety of conditions. 1-Menthol can be obtained by base catalyzed hydrolysis of the purified diastereomer with high optical purity.
