利用微波促进糖醛与叶立德(Ph3P=CHCOOEt)发生Wittig反应,立体选择性地合成了含有α,β-不饱和酯的糖烯类化合物,反应效率显著提高,使用不同的反应溶剂可实现对反应立体选择性的控制.并通过1H NMR中双键氢的偶合常数确定了产物的构型.
The Wittig reaction of furfural with Ph yl (CH 3 COOH) was promoted by microwave, and the α, β-unsaturated esters of vinylidene were stereoselectively synthesized. The reaction efficiency was significantly improved. Different reaction solvents were used to achieve the reaction Stereoselective control and the configuration of the product was confirmed by the coupling constants of double bond hydrogen in 1H NMR.
