new type of chiral separation materials, in this study, 6-amino-6-deoxyamylose was used as chiral starting material with which 10 derivatives were synthesized. The amino group in 6-amino-6-deoxyamylose was selectively acylated and then the hydroxyl groups were carbamoylated yielding amylose 6-amido-6-deoxy-2,3-bis(phenylcarbamate)s, which were employed as chiral selectors (CSs) for chiral stationary
为了开发新型手性分离材料,本研究以6-氨基-6-脱氧直链淀粉为手性起始原料,合成了10种衍生物。6-氨基-6-脱氧直链淀粉中的氨基被选择性酰化,然后羟基被氨基甲酰化,产生直链淀粉 6-氨基-6-脱氧-2,3-双(苯基氨基甲酸酯),用作手性选择剂 (CS)用于高效液相色谱的手性固定相。得到的 6-amido-6-deoxyamyloses 和直链淀粉 6-amido-6-deoxy-2,3-bis(phenylcarbamate)s 用 IR 表征,1H NMR和元素分析。对映体分离评估表明,大多数 CS 表现出中等的手性识别能力。直链淀粉 6-cyclohexylformamido-6-deoxy-2,3-bis(3,5-dimethylphenylcarbamate) 的 6-nonphenyl (6-nonPh) CS 对测试的手性分析物表现出最高的对映选择性;直链淀粉 6-(4-me
