Abstract
The X-ray crystal and modelled structures of the natural product 1-methyl-5,8-dihydroxynaphtho[2,3-c]furan-4,9-dione are presented. These data, in conjunction with modelling of the natural product ventilone G, confirm the preference for the 5,8-dihydroxynaphtho[2,3-c]furan-4,9-dione tautomers over those containing an isobenzofuran moiety and necessitate revision of the published structures of ventilone F and G.
