  Chemical Synthesis of Cyclodextrins by Using Intramolecular Glycosylation

  摘要：

  An efficient synthesis of cyclodextrins (CDs) by using the intramolecular glycosylation is demonstrated. alpha-CD, an alpha(1-->4)linked hexaglucoside, was prepared via a block condensation of three maltose units. A modified key maltose intermediate as a precursor to both glycosyl donor and acceptor components was prepared in 6 steps starting from maltose. All the glycosylation for chain elongation and cyclization of saccharides was carried out after tethering the donor to the acceptor by the phthaloyl bridge to give the desired saccharides in good yields with complete alpha-selectivity. delta-CD composed of 9 glucose units was synthesized by the same manner from three maltotriose units.

  Novel Molecular Clamp Method for Anomeric Stereocontrol of Glycosylation

  摘要：

  通过使用分子钳描述了立体控制糖基化，分子钳将糖基供体与受体结合在一起，并控制它们的空间排列。通过使用与糖基供体和受体的两个 6 位结合的邻苯二甲酰桥，以高产率和高选择性形成了δ（1 → 4）糖苷键。δ-选择性糖基化是通过使用连接到同一糖基供体和受体的相同 6 位的硅桥来实现的。此外，还介绍了这种方法在合成麦芽四糖衍生物中的应用。

  Stereocontrolled glycosylation is described by using a molecular clamp, which binds a glycosyl donor to an acceptor and controls their spatial arrangement. An α(1 → 4) glycosidic linkage was formed in a good yield with high selectivity by the use of phthaloyl bridge bound to both 6-positions of a glycosyl donor and an acceptor. β-Selective glycosylation was effected by the use of a silyl bridge attached to the same 6-positions of the same glycosyl donor and acceptor. Application of this method to the synthesis of a maltotetraose derivative is also described.
