    A short and practical methodology for conversion of unprotected D-glucose, maltose, cellobiose and lactose into the corresponding phenyl 4,6-O-benzylidine-per-O-acetylated-1,2-trans-thioglycosides is described. The protocol is based on the execution of five reaction steps (bromoacetylation, thiophenolysis under phase transfer catalysis conditions, deacetylation, benzylidenation and acetylation) in

  • Indirect and direct approaches in the synthesis of a new mono-6-O-benzyl methylated γ-cyclodextrin as chiral selector for enantioselective gas chromatography
    作者:Thomas Chaise、Pascal Cardinael、Séverine Tisse、Jean-Claude Combret、Jean-Philippe Bouillon
    DOI:10.1016/j.tetasy.2008.01.015
    日期:2008.2
    results clearly show the higher efficiency of the direct approach but demonstrate the feasibility of the insertion of a modified maltose derivative (indirect method). The new mono-6-O-modified methylated γ-cyclodextrin was used as a selector for the preparation of the new chiral stationary phase. Preliminary enantioselective gas chromatography applications are also reported.
    使用间接和直接方法合成了6 I - O-苄基-2 I-VIII,3 I-VIII,6 II-VIII-三毛-O-甲基-γ-环糊精。第一种间接策略由多步骤序列组成,包括全甲基化的α-环糊精的开环,6- O-苄基甲基化的二糖衍生物的链延长和大环化。直接方法处理选择性6--6 O-TBDMS对γ-环糊精的保护,全甲基化,脱保护和苄基化序列。结果清楚地表明了直接方法的较高效率,但证明了插入修饰的麦芽糖衍生物(间接方法)的可行性。新的单6-O-修饰的甲基化的γ-环糊精被用作制备新的手性固定相的选择剂。还报道了对映选择性气相色谱的初步应用。
  • Novel Molecular Clamp Method for Anomeric Stereocontrol of Glycosylation
    作者:Masahiro Wakao、Koichi Fukase、Shoichi Kusumoto
    DOI:10.1055/s-1999-2997
    日期:1999.12
    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.
    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。
