一般描述

γ-环糊精是一种环状低聚糖,含有八个通过α-1,4-糖苷键连接的葡萄糖单元。它可在水溶液中能与各种有机分子形成主客体复合物或包合物。因此,环糊精广泛用于食品和制药行业,用于敏感精细化学品的包合。

应用

γ-环糊精可用作:
  • 催化剂,通过硝酮与苯乙烯和肉桂酸酯的1, 3-偶极子环加成反应合成取代异恶唑烷。
  • 有机配体,通过生物相容性金属离子合成基于环糊精的金属有机框架。
  • 反应物,在存在NaH的条件下,通过烯丙基卤化物的过烯丙基化,合成O-过烯丙基化环糊精。

特点和优势

  • 绿色环保
  • 无生物毒性
  • 可生物降解

Novel supramolecular hydrogels were formed between pyrene-terminated poly(ethylene glycol) star polymers and γ-cyclodextrin (γ-CD), through the inclusion complexation of dimers of the pyrene terminals with γ-CD, where γ-CD was directly used as a supramolecular cross-linking reagent without any modification.
