A new reaction for carbohydrate elongation for synthesis of oligosaccharide using gold colloidal nanoparticles (GCNPs) has been developed. The gold core in this colloidal phase synthesis was prepared by a reduction of tetrachloroauric acid with 30,31-dithia-3,6,9,12,15,18,43,46,49,52,55,58-dodecaoxa-1,60-hexacontanediol. The presented alkanethionyl oligomeric ethylene glycol worked as a stabilizer
已经开发了使用金胶体纳米颗粒(GCNP)合成碳水化合物延长寡糖的新反应。通过用30,31-dithia-3,6,9,12,15,18,43,46,49,52,55,58-dodecaoxa-1还原四氯金酸来制备胶体相合成中的金核,60-六十六碳二烯二醇。所提供的链烷乙炔基低聚乙二醇用作GCNP的稳定剂和碳水化合物的化学延伸中的连接基。这种胶体相合成具有几个优点,例如(1)每个反应中残留的试剂和糖基供体都可以通过超滤或凝胶过滤柱色谱法轻松去除,(2)无需进一步纯化,(3)反应可以无需任何预处理,即可直接通过MALDI-TOF MS进行监测。实际上,
