The molecular recotwtion abilities of β-naphthoated β-CD derivatives as the host compounds were studied: 3-o-β-Naphthoyl-β-CD has a largely improved association constant with cyclohexanol than the corresponding 6-position substituted β-CD derivative has. On the other hand, the polarisablity and the sturcture of the gueset molecule are also important factors which affect the association constant. Cyclohexane may form the 1:2 type inclusion compound with the host compound in this report.
环糊精(CD)是由若干葡萄糖残基以α-(1,4)-糖苷键连接而成的大环化合物,它最大的特征是能在其分子空腔内结合多种有机、无机分子,因此 CD 及经化学修饰得到的一些衍生物可以较好地模拟天然酶的一些特性。对 CD 进行化学修饰的一个重要步骤往往是对它的羟基进行选择性的磺酰化。β-CD 是由7个葡萄糖残基组成的。
