摘要: β-蒎烯为原料、碱性高锰酸钾为氧化剂合成了诺蒎酸,诺蒎酸酸性脱水并重排开环得到4-异丙基-1,3-环己二烯酸(二氢枯茗酸)。二氢枯茗酸与氯化亚砜反应生成酰氯,再与各种醇反应生成了14个酯衍生物,通过IR、 1H NMR、MS对产物进行了结构鉴定。通过抑菌环法测试探讨了化合物的抑菌活性,结果表明,256 mg/L 时,除了化合物二氢枯茗酸异丁酯(5f),二氢枯茗酸叔丁酯(5g)对大肠杆菌的抑菌圈直径略小于市售杀菌剂新洁尔灭 9.67 mm 外,其他化合物的活性均高于市售新洁尔灭。

Abstract: Nopinic acid was synthesized using β-pinene as raw material and potassium permanganate as oxidant. After the dehydration of aqueous sulfuric acid, dihydrocumic acid was obtained. Fourteen esters were prepared by reactions of alcohols with dihydrocumic acid chloride. The preparation conditions were discussed and the structure of products were confirmed by IR, 1H NMR and MS. The antibacterial activity of products was tested through inhibition zone. Compared with the standard compound bromogeramine which diameter of inhibition zone is 9.67 mm, the compounds exhibit an excellent anti-bacterial activity against Escherichia coli(Gram-negative bacteria) except compounds 5f and 5g.

Key words: β-pinene, nopinic acid, dihydrocumic acid, ester derivatives, antibacterial activity
