摘要
本文报道了在混合溶剂中冠醚催化作用的Ｄａｒｅｎｓ酯缩合反应，并合成了四信芳族缩水甘油酸酯类化合物。产物经ＩＲ，＾１ＨＮＭＲ和元素分析鉴定，均与文献报道相符合。
The paper mainly studies the catalytic effect of crown ether for Darzens glycidic ester condensation of aromatic aldehydes with ethyl chlorocetate in mixed sovent system.The result showes that the yield of aromatic glycidic ester is 55.8～84.0% with DB—18—c—6 as catalyst,anhydrous ethanol and petroleum ether(b.p.90～120℃)as solvents and sodium ethoxide as a condensing agent.
