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.
