3-Methyl-4-phenylpyrrole from the Ants <i>Anochetus </i><i>kempfi</i> and <i>Anochetus mayri</i>

Abstract

The cephalic extracts of the ant Anochetus kempfi were found to contain 2,5-dimethyl-3-isoamylpyrazine (1) and 3-methyl-4-phenylpyrrole (2). The structures of these compounds were established from their spectral data and by comparison with synthetic samples. This is the first report of a phenylpyrrole found in an insect and only the third report of a pyrrole from ants.
