Clitolactone: a banana slug antifeedant from Clitocybe flaccida

Clitolactone, 5-(chloromethyl)-3-methyl-2(5H)-furanone, was isolated from sporocaps of the mushroom Clitocybe flaccida. The structure was determined by HRMS, EIMS, 1 H & 13 C NMR, 2D 1 H- 13 C COSY and 1 H- 1 H COSY. This mushroom is not eaten by the banana slug Ariolimax columbianus (Gould), a...

Description
Summary:Clitolactone, 5-(chloromethyl)-3-methyl-2(5H)-furanone, was isolated from sporocaps of the mushroom Clitocybe flaccida. The structure was determined by HRMS, EIMS, 1 H & 13 C NMR, 2D 1 H- 13 C COSY and 1 H- 1 H COSY. This mushroom is not eaten by the banana slug Ariolimax columbianus (Gould), a mycophagist from the temperate rain forests of the Pacific Northwest. Clitolactone acts as an antifeedant because these slugs rejected 1.0 cm 2 pieces of lettuce treated with 25 μg of clitolactone.
