new chiral stationary phase was tested against racemic mixtures of aromatic amino acids, after appropriate optimization of both the conditions of preparation of the plates and the mobile phase composition. The enantioselectivity values obtained for the studied compounds were higher than those reported in the literature for similar systems. The method employed here for the preparation of chiral HPTLC
Spi(τ-dec)的合成,是由L-spinacine(4,5,6,7-tetrahydro-1 H的选择性烷基化衍生而来的)本文首次描述了杂芳环的τ-氮处的-咪唑并[4,5-c]吡啶-6-羧酸),它具有10个碳原子的线性烃链。Spi(τ-dec)过去已成功用于制备手性配体交换高效液相色谱的自制手性柱。本文介绍了一种新方法,该方法在高性能薄层色谱(HPTLC)中使用Spi(τ-dec)作为手性选择剂:首先将商用疏水性板涂上Spi(τ-dec),然后进行处理。硫酸铜。在适当优化板的制备条件和流动相组成后,针对芳香族氨基酸的外消旋混合物测试了这种新的手性固定相的性能。研究化合物的对映选择性值高于文献报道的相似系统。经证明,这里用于制备手性HPTLC板的方法是实用,有效和廉价的。手性26:313–318,2014年。©2014 Wiley Periodicals,Inc.
