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.
1-薄荷醇可以通过将其转化为具有光学活性氨基酸的对映异构酯,然后对对映异构体进行色谱分离,从而从混合薄荷醇中轻松获得。对映异构酯的分离对载体或用作洗脱剂的溶剂相对不敏感,并且在各种条件下都可以进行令人满意的分离。通过对具有高光学纯度的纯化对映异构体进行碱催化水解,可以获得1-薄荷醇。
