β-iodo ethers has been synthesized from isosorbide. Isosorbide is a competitive starting material for various valuable derivatives by functionalization and/or substitution since it is a renewable and carbon neutral material that is produced on an industrial scale from sorbitol. The key step was the iodoetherification of isosorbide-derived glycals with a variety of oxygenated nucleophiles in the presence
已经从异山梨醇合成了一组 O-烷基化或 O-芳基化的 β-碘醚。异山梨醇是通过官能化和/或取代的各种有价值衍生物的竞争性起始材料,因为它是一种可再生且碳中性的材料,可从山梨醇以工业规模生产。关键步骤是在 N-碘代琥珀酰亚胺存在下,异山梨醇衍生的糖类与各种含氧亲核试剂的碘醚化。反式碘醚和乙酸盐以良好的收率获得,除去碘化物得到异山梨醇衍生物。这种新方法的有用性通过合成具有异山梨醇二聚体作为亲水基团的表面活性剂和制备结构上不寻常的双环脱水碳水化合物来说明。
