persulfate-mediated oxidative glycosylation system using p-methoxyphenyl (PMP) glycosides as bench-stable glycosyldonors is developed. This study shows that both K2S2O8 as an oxidant and Hf(OTf)4 as a Lewis acid catalyst play important roles in the oxidative activation of the PMP group into a potential leaving group. This convenient glycosylationprotocol proceeds under mild conditions and delivers a
开发了一种新型过硫酸盐介导的氧化糖基化系统,该系统使用对甲氧基苯基 (PMP) 糖苷作为稳定的糖基供体。该研究表明,作为氧化剂的K 2 S 2 O 8和作为路易斯酸催化剂的Hf(OTf) 4在将 PMP 基团氧化活化为潜在离去基团的过程中起着重要作用。这种方便的糖基化方案在温和条件下进行,并提供范围广泛的具有生物学和合成价值的糖缀合物,包括糖基氟化物。
