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.
