摘要: 利用高效液相色谱手性固定相对光学异构体分离分析日益受到人们的重视。高效液相色谱氨基酸酰胺型手性固定相对拆分对映异构体具有较好的效果。本文为了探讨该类手性固定相对氨基酸的拆分影响,用L-异亮氨酸叔丁酰胺型手性固定相,对6种DL氨基酸(丙氨酸、2-氨基-n-丁酸、缬氨酸、亮氨酸、苯丙氨酸和蛋氨酸)的18种衍生物进行了拆分,并讨论了其衍生物取代基对手性拆分的影响及从立体化学角度提出了手性拆分机理。实验结果表明,这种手性固定相对外消旋氨基酸衍生物有较好的拆分能力。

Abstract: Eighteen derivatives of six DLamino acid alanine, 2-amino-n-butanoic acid, va-line, leucine, phenylalanine, methionine of enantiomers were separated by L-isoleucine-t-butylamide type chiral bonded stationary phase (CSP) in HPLC. The experimental result showed that the chiral stationary phase had good resolution for the racemic α-amino acid derivatives. The performance of the structure of derivatives and composition of mobile phase for the resolution was examined. The probable mechanism for chiral recognition was proposed.
