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.

关键词: α,β-不饱和酯类, 糖类衍生物, 微波促进有机合成, 立体选择性Wittig反应

A stereoselectively controlled Wittig reaction of sugar aldehydes with Ph3P=CHCOOEt under microwave radiation was investigated. The reaction was curried out effectively and stereoselectively depending upon the solvents used, providing a convenient access to the glycosyl α,β-unsaturated esters. The structures and configurations of the products were determined according to the NMR spectra and the coupling constants of the olifenic protons (CH=CH).

Key words: α,β-unsaturated ester, carbohydrate derivatives, microwave assisted reaction, stereoselective Wittig reaction
