环糊精和糖淀粉衍生物与1,2-二酮的选择结合及对其氧化断裂反应的调节作用
Reactivity of Oxidative Cleavage of 1, 2 Diketones Mediated by Selective Binding of Cyclodextrins and Derivatives of Amylose
【摘要】 <正> 环糊精(CD)与糖淀粉都有相同的α-1,4糖苷键,近来以它们为宿主的研究日益广泛(?)它们的不同之处在于CD具有固定的内穴,尺寸随构成的葡萄糖残基数而变,而糖淀(?)包结过程中才发生构象变化,从无规线团或由线团连结的疏松螺旋变为间断螺旋的大(?)因此所形成的络合物比较松散,疏水受物整体能进入糖淀粉螺旋的内穴.
