Paragraph 0007; 0024; 0025; 0026; 0027; 0036; 0037, (2017/07/07)
The invention relates to a synthetic method of an organic compound. The synthetic method of bicyclo-[2.2.2]octane-1,4-dicarboxylic acid monomethyl easter is as follows: firstly, adopting sodium hydride, DMSS and 1,2-dibromoethane to synthesize the intermediate I; secondly, adopting the intermediate I, sodium acetate, ammourea hydrochloride and alcohol to synthesize semicarbazon; thirdly, adopting potassium hydroxide, diethylene glycol and semicarbazon to synthesize target diacid; fourthly, adopting target diacid, thionyl chloride and methanol to synthesize target diester; and fifthly, adopting target diester, potassium hydroxide and 95% of methanol water solution to synthesize the target product monoester. The invention has reasonable synthetic process route, mild process conditions, environment friendly, easy operation, low raw material cost, high product yield and excellent purity, and is applicable to industrial production and satisfies the application requirement of each industry.
