Pentylated cyclomaltohexaose (α-cyclodextrin) can be used as a chiral stationary phase for capillary g.l.c. in the range 40° to > 200°. Strong enantioselective molecular interactions are observed towards trifluoroacetylated carbohydrates, methyl glycosides, 1,4- and 1,5-anhydroalditols, polyols, and polyhydroxy acid methyl esters. Base-line resolution of enantiomers is achieved after only a few minutes.
摘要戊二醛化环戊二糖(α-环糊精)可用作毛细管glc在40°至> 200°范围内的手性固定相。观察到对三氟乙酰化的碳水化合物,甲基糖苷,1,4-和1,5-脱水醛糖醇,多元醇和多羟基酸甲酯的强对映选择性分子相互作用。对映体的基线拆分仅需几分钟即可实现。
