A two-step process for the transformation of readily available carbohydrate derivatives into acyclic C-nucleosides is described. The carbohydrate undergoes a scission process that is followed by the addition of aryl ketone derivatives, allowing the introduction of a variety of aryl rings. The resulting acyclic C-nucleosides are transformed into 2-deoxy cyclic pyranosides in good yield and excellent stereoselectivity.
描述了一种将易得的碳水化合物衍生物转化为无环 C-核苷的两步法。碳水化合物经历断裂过程,随后加入芳基酮衍生物,从而可以引入各种芳环。所得的无环 C-核苷以良好的产率和优异的立体选择性转化为 2-脱氧环吡喃糖苷。
