    • Process for the preparation of an enantiomerically enriched Schiff base wherein an amine is contacted with a carbonyl compound wherein the amine and/or the carbonyl compound is a chiral compound, to form a mixture of the enantiomers of the corresponding Schiff base wherein, if the amine is the chiral compound the carbonyl compound is an aromatic aldehyde; if the carbonyl compound is the chiral compound the amine is an aromatic amine and if both the amine and the carbonyl compound are chiral compounds, they in combination may have the same meanings as given above for both the chiral amine and the chiral carbonyl compound situation, and the mixture of enantiomers of the Schiff base is subjected to preparative chromatography on a stationary phase whereby separation of the enantiomers of the Schiff base is obtained. Preferably chiral Simulated Moving Bed chromatography is used.
    • 制备对映异构体富集席夫碱的方法,其中胺与羰基化合物接触,其中胺和/或羰基化合物是手性化合物,以形成相应希夫碱的对映异构体的混合物,其中如果胺 是手性化合物,羰基化合物是芳族醛; 如果羰基化合物是手性化合物,则胺是芳族胺,如果胺和羰基化合物都是手性化合物,它们的组合可以具有与手性胺和手性羰基化合物情况相同的含义, 并将席夫碱的对映异构体的混合物在固定相上进行制备色谱,由此获得希夫碱的对映异构体的分离。 优选使用手性模拟移动床层析法。
