Oxidation of maleopimaric anhydride methyl ester and trimethyl fumaropimarate. J. Braz. Chem. Soc. [online]. 2000, vol.11, n.1, pp. 59-63.

Ozonolysis of maleopimaric anhydride methyl ester in the presence of tetracyanoethylene led to an epoxide and an ozonide. Ozonolysis of the trimethyl fumaropimarate, followed by treatment with Me₂S, led to an epoxide, a diene, a keto-acid and an allylic oxidation product. Some of the compounds obtained were active against Staphylococcus aureus, Bacillus subtilis and Micrococcus luteus.
