Two diastereomeric chiral stationary phases (CSPs) were applied to the liquid chromatographic resolution of various racemic α-amino methyl esters, α-amino N,N-diethylamides and α-amino N-propylamides. The CSP incorporating (R)-3,3'-diphenyl-1,1'-binaphtyl and (R,R)-tartaric acid unit as chiral barriers did not show any chiral recognition. In contrast, the CSP incorporating (R)-3,3'-diphenyl-1,1'-binaphtyl
两种非对映异构手性固定相 (CSP) 用于液相色谱拆分各种外消旋 α-氨基甲酯、α-氨基 N,N-二乙基酰胺和 α-氨基 N-丙基酰胺。将 (R)-3,3'-diphenyl-1,1'-binaphtyl 和 (R,R)-酒石酸单元作为手性屏障的 CSP 没有显示出任何手性识别。相反,发现包含 (R)-3,3'-diphenyl-1,1'-binaphtyl 和 (S,S)-酒石酸单元作为手性屏障的 CSP 具有出色的手性识别能力,尤其是对于 α 的两种对映异构体-氨基N-丙基酰胺。在包含 (R)-3,3'-二苯基-1,1'-联萘基和 (S,S)-酒石酸单元的 CSP 上,一些 α-氨基甲酯和 α-氨基 N,N-二乙酰胺也被拆分.
