The reaction of 4-methoxycarbonylchroman-3-one with aryllead triacetates gave the 4-aryl derivatives after 3-4 h reaction times in moderate to good yields. Unexpectedly, 2,4-diarylated derivatives were also obtained after longer reaction times. The a

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-hydroxydihydro

Conventional HPLC analysis of the sesquiterpene aryl esters present in the crude extracts of the pathogenic basidiomycete Armillaria is complicated by difficulties in identification solely on the basis of retention time. On-line coupling of liquid ch
