value‐added ethers from bioderived aldehydes. Etherification of 5‐(hydroxymethyl)furfural with different aliphatic alcohols over acidic Zr–montmorillonite (Zr‐Mont) catalyst produced a mixture of 5‐(alkoxymethyl)furfural and 2‐(dialkoxymethyl)‐5‐(alkoxymethyl)furan. The latter was selectively converted back into 5‐(alkoxymethyl)furfural by treating it with water over the same catalyst. The synthesis of 2

etherification reaction of HMF and n-BuOH. Materials were synthesized with a Preyssler acid load of 12.5% w/w using the sol-gel technique, which improved surface areas and modulated their acid strength. Prepared materials were used as heterogeneous solid acid catalysts in the selective etherification of 5-hydroxymethylfurfural (HMF) to 5-butoxymethylfurfural (5BMF). The high catalyticperformance of the bulk
Herein, we investigated catalytic potential of a functionalized porous organic polymer bearing sulfonic acid groups (PDVTA-SO3H) to the etherification of 5-hydroxymethylfurfural (HMF) to 5-ethoxymethylfurfural (EMF) under solvent-free conditions. The PDVTA-SO3H material was synthesized via post-synthetic sulfonation of the porous co-polymer poly-divinylbenzene-co-triallylamine by chlorosulfonic acid
在此,我们研究了带有磺酸基团的功能化多孔有机聚合物 (PDVTA-SO 3 H) 在无溶剂条件下对 5-羟甲基糠醛 (HMF) 醚化为 5-乙氧基甲基糠醛 (EMF) 的催化潜力。PDVTA-SO 3 H 材料通过氯磺酸对多孔共聚物聚二乙烯基苯-共三烯丙基胺的后合成磺化合成。通过FT-IR、SEM、TG-DTG和N 2吸附等温线技术对PDVTA-SO 3 H的理化性质进行了表征。PDVTA-SO 3 H 具有高比表面积(591 m 2 g -1)和高密度的–SO3 H 基团(2.1 mmol g -1 )。通过Box-Behnken 响应面法优化反应条件在优化的条件下,PDVTA-SO 3 H催化剂表现出高效的催化活性,在110 ℃下30 min内HMF转化率为99.8%,EMF产率为87.5%。用过的PDVTA-SO 3 H催化剂很容易通过过滤回收并在循环运行中保持活性。

Prodrugs and derivatives of 5-hydoxymethyl-2-furfural (5-HMF) with protected or modified aldehyde and/or alcohol moieties are provided. The prodrugs or derivatives exhibit increased bioavailability, e.g. due to having extended half-lives in circulation. The drugs are therefore administered i) at lower doses and/or ii) less frequently than 5-HMF, while still maintaining the beneficial therapeutic effects of 5-HMF.
