two-step, one-pot procedure was developed for the conversion of primary alcohols to carboxylic acids. The alcohol was first treated with NaOCl and TEMPO under phase-transfer conditions, followed by NaClO2 oxidation in one pot. This reaction is applicable to a wide range of alcohols and the mild reaction conditions are compatible with many sensitive functional groups, including electron-rich aromatic rings
开发了一种方便的两步一锅法将伯醇转化为羧酸。首先在相转移条件下用 NaOCl 和 TEMPO 处理醇,然后在一锅中用 NaClO2 氧化。该反应适用于广泛的醇类,温和的反应条件与许多敏感的官能团相容,包括富电子芳环、酸不稳定的异丙叉缩酮和糖苷键,以及易氧化的硫缩醛、对甲氧基苄基和烯丙基部分。通过使用这种新的氧化方案,已经以高产率合成了几种糖胺聚糖,例如肝素、软骨素和透明质酸寡糖。
