Natural acetylenes. Part 52. Polyacetylenic acids and aromatic aldehydes from cultures of the fungus Camarophyllus virgineus(Wulfen ex fr.) Kummer

Abstract

The new polyacetylene HO·H₂C·[CC]₂·CH[graphic omitted]CH·CO₂H and p-(methylamimo)benzaldehyde, not found previously as a fungal metabolite, have been detected together with known natural polyacetylenes in extracts from culture fluids of C. virgineus. Hygrophoraceae species have not been reported previously as polyacetylene producers. The synthesis of some of the polyacetylenes is described.
