Method for preparing trans -7 and cis -9 - dodecadiene acetate

The invention discloses a method for preparing trans -7 and cis -9 - dodecadiene acetate, which comprises (1) adding 1 - 1 dichloroethylene in 2 - butyne tetrahydrofuran solution. The metal palladium compound, cuprous iodide and diisopropylamine undergo a coupling reaction to obtain 1 - chlorine -3 - yne -1 - hexene. (2) 20 °C (ClMgO) Under stirring, at CH. 2 )6 In MgCl, hexamethylphosphoric acid triamide and ferric acetyl acetonate are sequentially added, 1 - chlorine -3 - yne -1 - hexene is added dropwise to obtain the trans 7 - dodecene -9 - alkynol. (3) Zn powder was added to trans 7 - dodecene -9 - alkynol, stirred to obtain trans 7, cis 9 - dodecadienol, acetic anhydride and pyridine were added and stirred to obtain trans -7, cis -9 - dodecadiene acetate. The method provided by the invention is cheap and wide in source; the method has the advantages of short synthesis period, less steps, high yield, good stereoselectivity and simple post-treatment.
