Natural acetylenes. Part 54. Polyacetylenes from fungal cultures of some tricholomataceae and corticiaceae species

Abstract

Extracts from the culture fluids of Lentinus lepideus, Leucopaxillus giganteus, Lyophyllum decastes, and Peniophora resinosa were found to contain Me[C[graphic omitted]C]₃·CHCH·CH₂OH as the major polyacetylene. The first two contained also the corresponding methyl ether, which was synthesised, and the third contained the corresponding aldehyde. The new polyacetylene (+)-Me[CC]₃·CH[graphic omitted]CH·CH(OH) Et was isolated from the last culture.
