环糊精(Cyclodextrins)是一种大环化合物,其化学结构像一个空心圆锥体。在空腔内只有氢原于和糖苷氧原子,因而是亲脂的;而在环上有羟基存在故又具有亲水性。此种化合物可形成各种包结络合物(1),并可作为一种人工酶的模拟(2)。我们试用含有七个吡喃葡萄糖单元的β—环糊精(β—CD),在其羟基上的氢原子用辛基取代,生成辛基化的 Cyclodextrins are macrocyclic compounds that have a chemical structure like a hollow cone. In the cavity only hydrogen atoms and glycosides oxygen atom, which is lipophilic; and in the ring there is a hydroxyl and hydrophilic. Such compounds can form various inclusion complexes (1) and can be used as a model for artificial enzyme (2). We tried β-cyclodextrin (β-CD), which contains seven glucopyranose units, and the hydrogen atom on its hydroxyl group was replaced by octyl to generate octylated
