the separation of α-amino acid esters as benzophenone Schiff base derivatives on coated chiral stationary phases (CSPs) (Chiralcel OD-H, Chiralcel OD, Chiralpak AD-H, Chiralpak AD, and Chiralpak AS) or covalently immobilized CSPs (Chiralpak IA, Chiralpak IB, and Chiralpak IC) derived from polysaccharide derivatives is described. Benzophenone imine derivatives of α-amino acid esters were readily prepared
一种方便的液相色谱方法,用于在涂层手性固定相 (CSP)(Chiralcel OD-H、Chiralcel OD、Chiralpak AD-H、Chiralpak AD 和 Chiralpak AS)上或共价分离作为二苯甲酮席夫碱衍生物的 α-氨基酸酯描述了源自多糖衍生物的固定化 CSP(Chiralpak IA、Chiralpak IB 和 Chiralpak IC)。通过在 2-丙醇中搅拌二苯甲酮亚胺和 α-氨基酸酯的盐酸盐,很容易制备 α-氨基酸酯的二苯甲酮亚胺衍生物。色谱分离以1.0 mL/min的流速和254 nm的检测波长进行;0.5% 2-丙醇/己烷 (v/v) 用于 CSP。总的来说,Chiralpak IC 的分辨率优于其他 CSP。此外,
