Abstract: Nopinic acid (2-hydroxy-6,6-dimethyl bicyclo[3,1,1] heptane-2-carboxylic acid) has been synthesized through oxidation of β-pinene by potassium permanganate. The influences of the factors in the reaction were investigated. The optimum conditions for preparing nopinic acid are:n(β-pinene):n(KMnO4):n(NaOH) 1:2.5:1, water as solvent, reaction temperature 25-30℃ and reaction time 4-5 h. The yield is 35%.

Key words: β-pinene, nopinic acid, oxidation
