Pigments of Fungi. LVII. Structure and X-Ray Crystallographic Analysis of Dermocanarin 10, a New Naphthalene–Dihydroanthracenone Dimer from an Australian Dermocybe Toadstool

Abstract

The structure and absolute stereochemistry of the fungal metabolite dermocanarin 10 (2), which differs from all previous members of the dermocanarin group by virtue of the connectivity between the anthraquinone and dimethoxynaphthol rings, is deduced from spectroscopic data and confirmed by a single-crystal X-ray structure analysis.
