Abstract

Herein, a selective protocol for the complete removal of acetyl protecting groups from carbohydrate derivatives based on copper nanoparticles supported on activated carbon is presented. The deacetylation procedure occurs under neutral conditions, is applicable to a wide range of substrates and tolerates a variety of functional groups (e. g. azido, allyl and silyl groups). Quantitative yields of the deacetylated product were obtained for all evaluated derivatives using catalyst amounts between 1 and 10 mol%. As a special highlight, the dual behavior of the nanocatalyst in both deacetylation and click reactions is reported.

选择性碳水化合物脱乙酰化：基于纳米铜支撑颗粒的简单温和方法

本文介绍了一种基于活性炭支持的铜纳米粒子的选择性方案，用于完全去除碳水化合物衍生物中的乙酰保护基。脱乙酰过程在中性条件下进行，适用于多种底物，并可容忍多种官能团（如叠氮基、烯丙基和硅基）。催化剂用量在 1 至 10 摩尔%之间时，所有评估的衍生物都能获得定量的脱乙酰化产物。报告中特别强调了纳米催化剂在脱乙酰化和点击反应中的双重作用。
