The o-nitrophenyl group, a protecting group with latent activation potential, was used as a protecting group for the glycosidic position. It is stable to common conditions used in synthesis and can be activated for displacement and glycoside formation by an alcohol, using zinc chloride as a catalyst. Good to excellent yields of beta-glycosides of the important amino sugar N-acetylglucosamine were obtained
具有潜在活化潜能的保护基邻硝基苯基被用作糖苷位置的保护基。它对合成中常用的条件稳定,并且可以使用氯化锌作为催化剂,通过醇活化使其置换并形成糖苷。获得了重要的氨基糖N-乙酰基葡糖胺的β-糖苷的良好至优异的产率。提出了反应机理。
