Method for synthesizing (E)-7-dodecen-1-ol acetate

The invention belongs to the technical field of insect pheromone synthesis, and discloses a novel method for synthesizing (E)-7-dodecen-1-ol acetate. The method comprises the following steps: reactinga starting raw material 6-bromo-1-hexanol with 2,3-dihydropyran to obtain 1-tetrahydropyranyloxy-6-bromohexane, and carrying out a coupling reaction on the 1-tetrahydropyranyloxy-6-bromohexane and 1-hexyne in the presence of n-butyllithium to generate 1-tetrahydropyranyloxy-7-dodecyne; reducing the 1-tetrahydropyranyloxy-7-dodecyne by lithium aluminum hydroxide in diethylene glycol dimethyl etherto obtain (E)-tetrahydropyranyloxy-7-dodecene; and removing tetrahydropyran protecting groups by using p-toluenesulfonic acid to synthesize (E)-7-dodecen-1-ol acetate, and finally reacting the (E)-7-dodecen-1-ol acetate with acetyl chloride to obtain the target product (E)-7-dodecen-1-ol acetate. The method has the advantages of simple synthesis route, mild reaction conditions, and realization ofthe total yield reaching 49%.

New and simple syntheses of the attractants of the female melon fly, dacus cucurbitee

The attractant of the female melon fly, (E)-6-nonenyl acetate, and the two analogs, (E)-7-dodecenyl acetate and (E)-7-decenyl acetate were synthesized via hydrozirconation to control the regioselective coupling reactions and resulted in good yields.
