Isolongifolenone was synthesized by using heavy turpentine as the starting material. Firstly, the heavy turpentine was converted to isolongifolene by isomerization reaction with BF3 ( C2 H5 ) 2 O as catalyst. Isolongifolenone was finally obtained from isolongifolene by allylic oxidation with tert-butyl hydroperoxide ( TBHP) as oxidizer,Cu as catalyst and tert-butyl alcohol ( TBA) as solvent. By investigating the influence of different react conditions on the oxidation of isolongifolene,the optimum conditions were determined as follows:the mass fraction of Cu 3% ( based on the mass of isolongifolene ) , the mole ratio of TBHP and isolongifolene 3. 5∶1,the mass ratio of TBA and isolongifolene 1∶1,reaction temperature 80 ℃ and reaction time 12 h. The yield of isofolenone was over 93%,and the purity was 98. 75% under these conditions.
