context of the Mitsunobu reaction with adamantyl tags. HPLC experiments showed that molecules containing adamantyl groups were especially well retained on Sumichiral OA7500 β-methylated cyclodextrin bonded silica columns relative to many other types of molecules. Two new Mitsunobu reagents, bis-(1-adamantylmethyl) azodicarboxylate (BadMAD) and bis-(2-(1-adamantyl)ethyl) azodicarboxylate (BadEAD), were prepared
引入了一种新的分离带有环糊精结合基团的标签的方法,并在具有金刚烷基标签的Mitsunobu反应的背景下进行了举例说明。HPLC实验表明,相对于许多其他类型的分子,含有金刚烷基的分子在Sumichiral OA7500β-甲基化的环糊精键合硅胶柱上的保留特别好。制备了两种新的Mitsunobu试剂,双(1-金刚烷基甲基)偶氮二羧酸酯(BadMAD)和双(2-(1-金刚烷基)乙基)偶氮二羧酸酯(BadEAD),用于典型的Mitsunobu反应,并与β-甲基化的环糊精分离键合二氧化硅和标准二氧化硅。
