Sesquiterpene aryl esters from Armillaria tabescens

Sesquiterpene aryl esters from Armillaria tabescens

Five new sesquiterpene aryl esters based on the Δ 2, 3-protoilludane keleton were isolated from Armillaria tabescens grown in culture. These were characterized as 4-dehydro-14-hydroxydihydromelleolide, 4-dehydro-dihydromelleolide, 14-hydroxydihydromelleolide, 13-hydroxy-4-methoxymelleolide and 5β,10...

Description
Summary:Five new sesquiterpene aryl esters based on the Δ 2, 3-protoilludane keleton were isolated from Armillaria tabescens grown in culture. These were characterized as 4-dehydro-14-hydroxydihydromelleolide, 4-dehydro-dihydromelleolide, 14-hydroxydihydromelleolide, 13-hydroxy-4-methoxymelleolide and 5β,10α-dihydroxy-1-orsellinate-dihydromelleolide. The structures of these compounds was established by collective NMR techniques.
