, (2019/03/08)
The invention relates to the technical field of synthesis of compounds and specifically relates to a production process of high-purity and high-yield spirodiclofen. The production process comprises the following steps: performing an addition reaction on cyclohexanone which is taken as a starting material, so as to obtain 1-cyano-cyclohexanol; hydrolyzing and esterifying the 1-cyano-cyclohexanol, so as to obtain 1-hydroxylethyl formate; performing a condensation ring-closing reaction on the 1-hydroxylethyl formate, so as to obtain an intermediate caproate; and performing a reaction on the caproate and 2, 2-dimethylbutyryl chloride, so as to obtain the spirodiclofen. According to the production process, the problem in the prior art that the prepared spirodiclofen is low in purity and yield is solved; the spirodiclofen prepared by adopting the production process is high in purity and yield; and in addition, the raw material for preparing the spirodiclofen is easily obtained, and the operation is convenient.
