The invention belongs to the field of fine chemistry, and particularly relates to a synthetic method of 4-methyl-4-(cis-3-hexenyl)-4-butyrolactone. The method comprises the following steps: taking leaf alcohol as a starting material, enabling the leaf alcohol to react with thionyl chloride to generate cis-1-chloro-3-hexene, first reacting with metal magnesium to obtain a cis-3-hexenyl Grignard reagent, then reacting with acetyl chloride to generate cis-5-hexene-2-ketone, and then reacting with methyl propiolate in the presence of n-butyllithium to obtain cis-4-methy-4-hydroxyl-7-decene-2-acetylenic acid methyl ester, and finally directly performing the reaction cyclization with NaBH4 under the catalysis of CuCl to obtain the 4-methyl-4-(cis-3-hexenyl)-4-butyrolactone. The method is environment-friendly, low in cost and suitable for the industrialization production.
