  Simplifying Oligosaccharide Synthesis:  Efficient Synthesis of Lactosamine and Siaylated Lactosamine Oligosaccharide Donors

  摘要：

  A practical sequence is described for converting D-glucosamine into peracetylated Gal(beta-1,4)-GlcNTroc(beta1-S)Ph and Neu5Ac(alpha-2,3)Gal(beta-1,4)GlcNTroc(beta1-S)Ph building blocks using a synthetic strategy based on chemoenzymatic oligosaccharide synthesis. The known trichloroethoxycarbonyl, N-Troc, protecting group was selected as a suitable protecting group for both enzymatic and chemical reaction conditions. These oligosaccharide building blocks proved effective donors for the,beta-selective glycosylation of the unreactive OH-3 of a polymeric PEG-bound acceptor and for the axial OH-2 of a mannose acceptor in good yields. The resulting complex oligosaccharides are useful for vaccine and pharmaceutical applications.

  Lewis X-O -Core-1苏氨酸的合成：O-连接的Lewis X糖肽的结构单元

  摘要：

  LewisX（LeX）是一种分支的三糖Galβ1→4（Fucα1→3）GlcNAc，在许多细胞表面糖蛋白上表达，在先天性和适应性免疫应答中起关键作用。然而，携带LeX的糖肽的有效合成仍然是LeX决定簇结构功能研究的主要限制。在这里我们报告了使用区域选择性的1-苯亚磺酰基哌啶/三氟甲磺酸酐促进的[3 + 2]糖基化的LeX五糖1的总合成。Fmoc-苏氨酸氨基酸的存在促进了五糖在固相肽合成中的掺入，提供了通往多种O-连接的LeX糖肽的途径。所描述的方法广泛适用于合成多种复杂的糖肽，这些糖肽包含O-连接的LeX或唾液酸化的LewisX（sLeX）。

• Design and Synthesis of a Novel Ganglioside Ligand for Influenza A Viruses †

  A novel ganglioside bearing Neua2-3Gal and Neua2-6Gal structures as distal sequences was designed as a ligand for influenza A viruses. The efficient synthesis of the designed ganglioside was accomplished by employing the cassette coupling approach as a key reaction, which was executed between the non-reducing end of the oligosaccharide and the cyclic glucosylceramide moiety. Examination of its binding activity to influenza A viruses revealed that the new ligand is recognized by Neua2-3 and 2-6 type viruses.

  disaccharides or glycoconjugates with high α‐selectivity and yields (77–97 %) using a trans‐fused cyclic 3,4‐O‐disiloxane protecting group and TsOH⋅H2O (1 mol %) as a catalyst. Control of the anomeric selectivity arises from conformational locking of the intermediate oxacarbenium cation. Glucals outperform rhamnals because the C6 side‐chain conformation augments the selectivity.

  2-(2-Pyridyldithio-3-butenyl) glycosides react with carbohydrate-based thiols in a two-step process involving sulfenyl transfer followed by desulfurative 2,3-allylic rearrangement, promoted by either triphenylphosphine or silver nitrate, to give novel saccharide mimetics. In an alternative embodiment of the same chemistry anomeric thiols are coupled with carbohydrates derivatized in the form of 2-

  A novel post-translational modification of threonine, β-N-acetylglucosaminyl-phosphate, was recently discovered on assembly protein AP180, a protein which plays a crucial role in clathrin coated vesicle formation in synaptic vesicle endocytosis (SVE). Herein, we report studies aimed at probing the effect of this modification on binding to proteins in rat brain lysate using pull down experiments with peptide fragments of AP180.
