Paragraph 0025, (2019/05/15)
The invention discloses a method for preparing a moth pheromone pickles, characterized in that comprises the following steps: S1, taking eleven vinyl alcohol synthesis undecene - 11 - ol benzoates; S2, will take Hendecane glycol synthesis Hendecane mono benzoates; S3, synthetic undecanal - 11 - ol benzoates; S4, synthetic cis - 11 - hexadecenoic - 1 - ol benzoates; S5, synthetic cis - 11 - hexadecenoic - 1 - ol; S6, synthetic cis - 11 - sixteen [...]; S7, synthetic cis - 11 - hexadecenoic - 1 - ethoxylate ester; S8, the composition is mixed, moth pheromone shall pickles. The present invention, adopts a double-sodamide as alkali, phosphine ye li? deodorant pentane as raw material with undecanal - 11 - alcohol benzoate reaction occurs, the reaction yield is as high as 89%, and syn-form isomer content of 98% or more, and the synthetic method is simple.

Paragraph 0022, (2018/09/12)
The invention belongs to the technical field of chemical synthesis, in particular relates to a moth pheromone of the pickles synthetic method, comprises the following steps: 1) in the organic solvent, 11 - bromo - 1 - [...] with triphenylphosphine reaction to produce bromo Hendecane [...]; 2) under the protection of nitrogen, step 1) obtained in the bromo Hendecane [...] with valeraldehyde, sodium ethoxide in tetrahydrofuran solvent to react to generate cis - 11 - sixteen-carbon vinyl alcohol; 3) in the dichloromethane solution in, step 2) obtained in the cis - 11 - sixteen carbon alcohol with the occurrence chloro-chromic acid pyridine salt to the oxidizing reaction to produce cis - 11 - sixteen [...]; 4) in dichloromethane in, step 2) obtained in the cis - 11 - sixteen carbon alcohol with acetic anhydride, pyridine reaction to produce cis - 11 - sixteen-carbon vinyl alcohol acetate. The invention uses inexpensive and easily obtained 11 - bromo - 1 - [...] as the starting material, the synthesis step is reduced, simplifies the synthesis process, the product yield is high, the reaction conditions are mild and controllable, low requirements on equipment, can be used for industrial production.
