Two selectors derived from [(S)-1-(1-naphthyl)ethyl]amine and (S)-leucine have been chemically bonded to one another and the resulting chiral auxiliary linked covalently to silica gel, to produce a new chiral stationary phase (CSP) for the HPLC resolution of enantiomers. The CSP is able to separate the enantiomers of some selected racemic compounds: both those resolved by Oi’s CSP derived from [1
[[ S ] -1-(1-萘基)乙基]胺和(S)-亮氨酸衍生的两个选择剂已彼此化学键合,所得手性助剂与硅胶共价连接,从而产生新的手性固定相(CSP)用于对映异构体的HPLC拆分。CSP能够分离某些选定的外消旋化合物的对映异构体:由Oi's CSP拆分的对映异构体衍生自[1-(1-萘基)乙基]胺}和由Pirkle's CSP拆分的对映异构体[源自N-(3,5 -二硝基苯甲酰基)亮氨酸]。获得的结果表明,CSP具有有效的双选择器系统的特性。
