Trogoderma granarium sex pheromone and preparation method thereof

The invention discloses trogoderma granarium sex pheromone and a preparation method thereof. The preparation method comprises the following steps: enabling (R)-2-methylbutanol to react with 5-sulfydryl-1-phenyltetrazole Mitsnobu to obtain A; enabling A to react with peroxy acid to obtain B; enabling 1,3-propanediol to react with benzyl chloride under an alkaline condition to obtain C; oxidizing Cto obtain a compound D; enabling B to react with D and hexamethyldisilamine lithium salt to obtain E; catalytically hydrogenating E by virtue of palladium to obtain F; enabling F, iodine, tertiary phosphine and imidazole to obtain G; obtaining H by using 1,8-octylene glycol and benzyl chloride and alkali; oxidizing H to obtain I; obtaining J by using I, carbon tetrabromide and triphenylphosphine Corey-Fush; obtaining K by using J and strong alkali; obtaining L by using K and G and alkali; obtaining M by using L, ethyl mercaptan and boron trifluoride diethyl etherate solution; catalytically hydrogenating M by virtue of metal to obtain N; and oxidizing N to obtain a target product, wherein a chemical name of the target product is (R,Z)-14-methylhexadeca-8-ene-1-aldehyde, thus obtaining the trogoderma granarium sex pheromone. The preparation method disclosed by the invention is low in cost and high in yield.
