Pigmentosin A,a New Naphthopyrone from the Lichen Hypotrachyna immaculata

Elix, John; Wardlaw, Judith


The new naphthopyrone, pigmentosin A 1, has been isolated from the lichen Hypotrachyna immaculata and its structure elucidated using multidimensional NMR spectroscopic methods, including high-field (600 MHz) gHMBC and gHMQC experiments. This compound is the first lichen metabolite known to contain a bisnaphthopyrone moiety in its structure.
