New 2- and 3-methoxyquinopimaric-acid derivatives were synthesized by a Diels–Alder reaction of levopimaric acid and 2-methoxy-1,4-benzoquinone. The reaction rate and regioselectivity of the cycloaddition were increased significantly by using a Bmim·BF4 catalyst. Photolysis of 3-methoxyquinopimaric acid produced new scaffold derivatives. The compounds were characterized by NMR spectroscopy and elemental analysis.
