说明

γ-环糊精是含有通过α-1,4-糖苷键连接的八个葡萄糖单元的环状寡糖。它可以在具有各种有机分子的水溶液中形成主客体或包合物。因此,环糊精广泛用于食品和制药工业,用于敏感精细化学品的微胶囊化。

一般描述

γ-Cyclodextrin is a cyclic oligosaccharide containing eight glucose units linked by α-1,4-glycosidic bonds. It can form host-guest or inclusion complexes in aqueous solutions with various organic molecules. As a result, cyclodextrins are widely used in the food and pharmaceutical industries for the microencapsulation of sensitive fine chemicals.
 

应用

γ-Cyclodextrin can be used as:
  • A catalyst to synthesize substituted isoxazolidines via 1,3-dipolar cycloaddition of nitrones with styrenes and cinnamates.
  • An organic ligand to synthesize cyclodextrin-based metal-organic frameworks using biocompatible metal ions.
  • A reactant to synthesize O-perallylated cyclodextrins via perallylation with allyl halides in the presence of NaH.

特点和优势

  • Green and environment-friendly
  • No biological toxicity
  • Biodegradable
