摘 要:以可再生资源为原料,利用高效原子经济性的反应设计合成了新的功能分子。首先以果糖为原料,一步合成2,5-二甲酰基呋喃(DFF),收率 41%;再以DFF 和丙烯酸甲酯为原料进行Morita-Baylis-Hillmann(MBH)反应,在不同溶剂条件下选择性合成单甲酰基和双甲酰基加成产物1 和2:以二氧六环-水(V∶V=1∶1)为溶剂可同时获得单甲酰基和双甲酰基发生MBH 反应的产物1 和2,收率分别为 46% 和 37%;以甲醇为溶剂则选择性获得单甲酰基发生MBH 反应的产物1,收率 32%。产物用1H NMR进行了结构表征确证。

Abstract:It is of great significance to synthesize functional molecules via highly efficient and atom-economic reactions by using renewable resource materials. Herein, firstly, 2,5-diformyl furan (DFF) was synthesized from fructose in one step with a yield of 41%. Then, MBH reactions were conducted between DFF and methyl acrylate,and selective products in different solvents were obtained. When 1,4-dioxane/water (V∶V=1∶1) was utilized, both mono-acrylate and di-acrylate products were obtained at yield of 46% and 37%, respectively; while the sole methanol solvent gave only mono-acrylate with a yield of 32%. All the products were characterized by 1H NMR. The synthesized functional acrylates may further undergo reactions to prepare more valuable small molecules as well as polymers.
Key words:functional acrylates; MBH reaction; 2,5-diformyl furan (DFF); selectivity
