-
摘要: 目的 藜芦醛是一类重要的医药中间体和化工原料, 在总结其常见合成方法的基础上, 进一步研究更加高效的合成路线, 为藜芦醛的应用打下良好基础.方法 以甲基丁香酚为原料经Triton B催化的烯烃异构化反应和臭氧氧化/还原反应合成藜芦醛.结果 探索了反应时间、反应温度、催化剂用量等对实验的影响, 筛选出制备藜芦醛的最优化条件, 两步反应总产率达到64%.结论 此合成路线所用原料易得, 反应条件温和, 有一定的工业应用价值.Abstract: Objective Veratraldehyde is an important pharmaceutical intermediate and chemical raw material. Taking common synthetic methods of Veratraldehyde into consideration, the study is aimed to further investigate a more efficient synthetic route in order to provide a solid foundation for the application of Veratraldehyde.Me thods This article introduces an alternative method based on the Triton-B catalyzed olefin isomerization of methyl Eugenol followed by ozonation/reduction reaction.Re s ults In the experiment, the optimal conditions was selected by investigating the influence of reaction time, reaction temperature and catalyst dosage on the yield of Veratraldehyde. The total yield of this 2-step reactions was 64%. Conclus ion The above-mentioned synthesis method only requires raw materials that are easily acquired and its relative reaction conditions are mild, thus it will provide values in the industrial applications.
