Synthesis method of laspeyresia pomonella sex pheromone
InactiveCN110078593AConform to structural featuresEfficient synthesisGroup 4/14 element organic compoundsOrganic compound preparationAcetic anhydrideSynthesis methods
The invention relates to a synthesis method of laspeyresi pomonella sex pheromone. The method comprises the steps as follows: (1) methanol is added to methyl sorbate as a raw material, and an intermediate A sorbic alcohol is obtained through 5% palladium-carbon catalytic hydrogenation reduction; (2) the intermediate A sorbitol obtained in (1) and acetic anhydride are subjected to a reaction in ethyl acetate, triethylamine and water to obtain an intermediate B sorbic acetate; (3) 6-chlorohexanol is subjected to a reaction with trimethylchlorosilane in toluene in the presence of ethyl acetate and triethylamine, after the reaction, water is added, stirring and layering are performed, and an intermediate C6-chlorohexanol trimethylsilyl ester is obtained; (4) the intermediate B sorbic acetate and the intermediate C6-chlorohexanol trimethylsilyl ester are subjected to a reaction with sodium sand in a toluene solution, then, water and sulfuric acid are dropwise added, layering and rectification are performed, and a target product E8,E10-dodecadiene-1-ol is obtained. The synthesis method has the advantages as follows: the laspeyresi pomonella sex pheromone is synthesized from available rawmaterials, the reaction route is short, and the selectivity and product yield can be increased.
