Six pinonic acid esters were synthesized from one-pot ozonolysis reaction using α-pinene and alcohol as materials, dichloromethane as solvent and N,N-dimethyl-4-aminopyridine (DMAP) as catalyst with the yield of 60%. The reaction temperature was 40 ℃ and reaction time was 4 h. This method is a convenient and efficient way to synthesize pinonic acid esters, such as simple operation, mild conditions and high yields. The structures of the six pinonic acid esters were identified by IR, NMR and MS techniques.

Key words: DMAP, one-pot synthesis, ozonolysis, pinonic acid ester
