  摘要：

  The synthesis of the trisaccharide allyl 2-O-(alpha -L-arabinofuranosyl)-6-O-(alpha -D-mannopyranosyl)-beta -D-mannopyranoside is reported. Stereoselective glycosylation at C-6 of a non-protected allyl beta -mannoside with the acetylated alpha -D-mannosyl bromide gave the alpha-(1 --> 6)-disaccharide as the main product and the crystalline 3,6-branched trisaccharide as minor compound. Further glycosylation of the 2,3 diol (1 --> 6) disaccharide with L-arabinofuranosyl bromide furnished a mixture of 3-O- and 2-O-alpha -L-Ara-trisaccharides from which the title compound was isolated.

  A site-specific deprotonation followed by alkylations and acylations of sugar hemiacetals to the corresponding alkyl glycosides and acylated sugars in aqueous solutions is disclosed herein. Pyridoneimine as a new base is developed to mediate the deprotonation of readily available sugar hemiacetals and further reactions with alkylation and acylation agents.

The stereochemistry dramatically affected fragmentation which was dependent on four relative stereochemical arrangements: (1) the relationship between the hydroxyl group at position 2 and the anomeric configuration, (2) a cis relationship

• Joining Hydroxyazobenzene and Mannose under Mitsunobu Conditions
  作者：Julia Hain、Vijayanand Chandrasekaran、Thisbe K. Lindhorst

  日期：2015.4

  The Mitsunobu reaction has been revisited to join hydroxyazobenzene and mannose derivatives to supply photoswitchable glycoconjugates. These are suited to modulating and controlling carbohydrate‐lectin interactions, as well as to switching bacterial adhesion to surfaces. Employing hydroxyazobenzene in a Mitsunobu protocol, free mannose led to a mixture of azobenzene pyranosides and furanosides. Protected

  再次讨论了Mitsunobu反应，以连接羟基偶氮苯和甘露糖衍生物，以提供可光转换的糖缀合物。这些适用于调节和控制碳水化合物-凝集素的相互作用，以及切换细菌对表面的粘附。在Mitsunobu方案中使用羟基偶氮苯，游离甘露糖会生成偶氮苯吡喃糖苷和呋喃糖苷的混合物。受保护的还原性甘露糖衍生物可提供高收率的偶氮苯β- D-甘露糖吡喃糖苷，未保护的烷基α- D-甘露糖苷可一步转化为6 - O-偶氮苯修饰的糖苷。因此，可以在Mitsunobu条件下获得有价值的“甜味开关”，这需要最少（或不需要）保护基化学反应。
