摘要：

室温超声辐射下，4-二甲氨基吡啶(DMAP)作催化剂，二环己基碳二亚胺(DCC)作脱水剂，不需保护异阿魏酸分子中的羟基，异阿魏酸和对氯苯酚的一步反应直接合成了异阿魏酸对氯苯酚酯。 在n(异阿魏酸)∶n(对氯苯酚)∶n(DCC)∶n(DMAP)=1∶1.2∶1.2∶0.1混合时，室温超声反应2.5 h，得产率76.2%。 目标化合物的结构经元素分析、1H NMR和IR测试技术得到确证。 缩短了反应时间，提高了产率。

Abstract:

4-Chlorophenyl isoferulate was synthesized in onestep from isoferulic acid and 4-chlorophenol without the protection of the hydroxyl of isoferulic acid in the presence of 4-dimethylpyridine(DMAP) as catalyst and dicyclohexylcarbodiimide(DCC) as dehydrating agent under ultrasonic irradiation at room temperature. When reactants were mixed in a n(isoferulic acid)∶n(4-chlorophenol)∶n(DCC)∶n(DMAP)=1∶1.2∶1.2∶0.1, and exposed to ultrasonic irradiation for 2.5 h, the yield was 76.2%. The structure of the product was confirmed by elemental analysis, 1H NMR and IR. This method avoids the long reaction time and increases the yield compared with traditional synthetic method.

Key words: 4-chlorophenyl isoferulate, dicyclohexylcarbodiimide, 4-dimethylpyridine, ultrasonic irradiation
