General description

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.

Application

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.

Features and Benefits

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