Synthetic method of aliphatic pentacyclic dianhydride

The invention discloses a synthetic method of aliphatic pentacyclic dianhydride, and particularly relates to a synthetic method of pentacyclic [8.2. 1.14, 702, 903, 8] tetradecane-5, 6, 11, 12-tetracarboxylic dianhydride. The invention belongs to the field of preparation methods of fine chemicals. Maleic anhydride and cyclopentadiene are used as initial raw materials, an intermediate product norbornene dianhydride is synthesized through a 1, 4-addition reaction at a low temperature, then a solvent and a photocatalyst are added, the reaction process is monitored through HPLC under the illumination condition of a single-wavelength light source, and after the reaction is finished, a white solid is obtained through aftertreatment. The method disclosed by the invention is simple to operate, high in synthesis yield and few in byproducts. 本发明公开了一种脂肪族五环二酐的合成方法，具体是五环[8.2.1.100]十四烷-5,6,11,12-四羧酸二酐的合成方法。本发明属于精细化学品制备方法领域。本发明以顺丁烯二酸酐和环戊二烯为起始原料，在低温下经1,4-加成反应合成中间产物降冰片烯二酸酐，然后再加入溶剂和光催化剂，在单一波长光源的光照条件下，HPLC监测反应进程，反应结束后，后处理得到白色固体
