  Divergent Strategy for the Synthesis of α2-3-Linked Sialo-oligosaccharide Libraries Using a Neu5TFA-(α2-3)-Gal Building Block

  摘要：

  A novel Neu5TFA-(alpha 2-3)-Gal building block with removable protecting group at N5' was introduced and used in the divergent synthesis of a library of N-acetyl and N-glycolyl derivatives of oligosaccharides related to sialyl-(alpha 2-3)-N-acetyl-lactosamine and sialyl-(alpha 2-3)-N-acetyl-isolactosamine, with or without sulfate at O6 of glucosamine residue.

  antigens are a family of widely distributed histo-blood group antigens sharing the Siaα2,3(GalNAcβ1,4)Gal trisaccharide determinant. Despite their significant biological importance, the synthesis of these complex carbohydrate antigens is challenging. Herein, we report a highly efficient and green synthesis of diverse Sda antigens with different underlying structures and sialic acid forms utilizing 6 multienzyme

  Sd a抗原是共享Siaα2,3（GalNAcβ1,4）Gal三糖决定簇的广泛分布的组织血型抗原家族。尽管它们具有重要的生物学重要性，但是这些复杂碳水化合物抗原的合成仍具有挑战性。在此，我们报告了利用6种多酶级联反应系统高效，绿色合成具有不同基础结构和唾液酸形式的多种Sd a抗原的方法。多酶级联方法结合了糖核苷酸供体产生酶和糖基转移酶，为从简单的单糖结构单元快速组装复杂的聚糖提供了一种有效而方便的方法。
