Herein, we present a facile synthetic process for producing biomass-derived isosorbide (ISB) dioxides using dimethyl dioxirane (DMDO) as an efficient oxidizing agent, which was generated in situ from acetone and KHSO . To achieve high conversion and product yield, the KHSO concentration, KHSO flow rate, and reaction temperature were optimized. Under the optimal conditions, rapid and efficient epoxidation using the in situ-generated DMDO was observed under ultrasonication, yielding the desired product within 35 min at 0 °C. This study offers a convenient and efficient method for generating biomass-derived ISB building blocks, which have significant potential for the fabrication of bioplastics.
在此，我们展示了一种简便的合成方法，以丙酮和KHSO原位生成的二甲基二氧杂环丙烷（DMDO）作为高效氧化剂，用于生产生物质衍生的异山梨醇（ISB）二氧化物。为实现高转化率和产物收率，对KHSO浓度、KHSO流速和反应温度进行了优化。在最佳条件下，原位生成的DMDO在超声处理下能快速高效地进行环氧化反应，在0℃下35分钟内即可得到所需产物。本研究提供了一种便捷高效的方法来生成生物质衍生的ISB结构单元，其在生物塑料制造方面具有巨大潜力。
