  A New Approach for the Synthesis of Hyperbranched N-Glycan Core Structures from Locust Bean Gum

  摘要：

  A novel protocol for the synthesis of general N-glycan core structures was established by means of Man beta(1 -> 4)Man peracetate derived from a naturally abundant locust bean gum as a key starting material. Phenyl (2-O-benzy1-4,6-O-benzylidine-beta-D-mannopyranosyl)-(1 -> 4)-3,6-di-O-benzyl-2-azido-2-deoxy-1-thio-beta-D-glucopyranoside facilitated the synthesis of key intermediates leading to hyperbranched N-glycan core structures.
