Natural acetylenes. Part XLII. Novel C7, C8, C9, and C10 polyacetylenes from fungal cultures

Abstract

The diynol (–)-EtCH(OH)·[CC]₂H has been found in Gymnopilus spectabilis, the triynol and triynoic acid Me[CC]₃R (R = CH₂·OH or CO₂H) have been found in Psilocybe merdaria, Kuehneromyces mutabilis, Russula vesca, and Ramaria flava, and the acids H[CC]₃·CH₂·CH₂·CO₂H and HO₂C·CH[graphic omitted]CH·[CC]₂·CH₂·CH₂·CO₂H have been obtained from Serpula lacrymans cultures. The Strophariaceae, Russulaceae, and Gomphaceae families have not been reported previously as polyacetylene producers.
