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
