A site-specific deprotonation followed by alkylations and acylations of sugar hemiacetals to the corresponding alkyl glycosides and acylated sugars in aqueous solutions is disclosed herein. Pyridoneimine as a new base is developed to mediate the deprotonation of readily available sugar hemiacetals and further reactions with alkylation and acylation agents.
本文公开了在水溶液中进行位点特异性去质子化,随后将糖半缩醛烷基化和酰化为相应的烷基糖苷和酰化糖。吡啶酮亚胺作为一种新的碱被开发用于介导容易获得的糖半缩醛的去质子化以及与烷基化和酰化剂的进一步反应。
