An efficient, simple, scalable and atom efficient method for the synthesis of 2,5-dihydroxymethylfuran (DHMF) and 5-hydroxymethylfuranoic acid, as sodium salt (HMFA), in 80% yield from 5-hydroxymethylfurfural (HMF) in water using NaOH (0.9 eq.) via a Cannizzaro reaction is described. Both the building blocks DHMF and HMFA were successfully isolated merely using selective crystallisation.
一种高效、简单、可扩展且原子经济的方法被描述用于在水中使用NaOH(0.9当量)通过Cannizzaro反应从5-羟甲基呋喃(HMF)合成2,5-二羟甲基呋喃(DHMF)和5-羟甲基呋喃酸钠盐(HMFA),产率为80%。两个构建块DHMF和HMFA成功地仅通过选择性结晶分离。
