preparation of polyfluorinated carbohydrates. A limited number of fluorohexopyranosides have been used in biological investigations because of the synthetic challenge they present. Hence, we report the synthesis of fluorinated homodimer, fluorodisaccharides, C‐terminal fluoroglycopeptides, lipoic acid fluoroglycoconjugate and trifluoroallopyranoside derivatives functionalized at C‐6. Our strategy uses levoglucosan
人们对制备多氟化碳水化合物的兴趣日益增长。由于其存在的合成挑战,已将有限数量的氟己基吡喃糖苷用于生物学研究。因此,我们报告了在C-6上官能化的氟化同二聚体,氟二糖,C端氟糖肽,硫辛酸氟糖缀合物和三氟吡喃糖苷衍生物的合成。我们的策略使用左旋葡聚糖作为廉价的原料,并促进了具有多个CF键的复杂碳水化合物类似物的制备方法。我们合成途径的挑战集中在有效制备关键的1,6-脱水-2,4-二脱氧-二氟吡喃葡萄糖上,并着重于实现三氟戊吡喃糖供体的困难糖基化。
