Abstract: The myrcene and 1,4-benzoquinone are used as raw materials to synthesize naphthalene catechol derivatives naphthalene-1,4-diol. Using GC-MS, melting point determination, FT-IR, 1HNMR as detection means, the structure of the product is identified as 6-(4-methyl-pent-3-enyl)-5,8-dihydronaphthalene-1,4-diol. Diels-Alder reaction is affected by different type of catalysts, catalyst amount, reaction solvent, reaction temperature, the ratio of raw materials and reaction time. It is concluded that the suitable molar ratio of myrcene to 1,4-benzoquinone is 1:1,while the fittest catalyst is ZnCl2, the dosage is 15% of 1,4-benzoquinone. Ethyl acetate is chosen as solvent and the reaction temperature is 80℃, reaction time is 10 h. Under this condition, the selectivity and yield of product reached 81.0% separately.
