摘要 从红菇中分离到了三种新的倍半萜,呋喃醚 A、呋喃沙酮 A 和 sardonialactone A (7-hydroxyblennin A),以及乳醛、velerolactone、两种已知的呋喃醇乳妥鲁芬 A 和 cerevisterol。通过光谱数据和通过化学转化与已知化合物的相关性来阐明结构和立体化学。
The exomethylene furan alcohol 2, which is formed when fatty acid esters of velutinal 1 isolated from Lactarius species are degraded on silicagel, correlates the absolute configuration of isovelleral 5a with that of other sesquiterpenes isolated from Lactarius sp.

An ethanol extract of Lactarius necator gave 3,8-oxa-13-hydroxy-lactar-6-en-5-oic acid gamma-lactone and furanether A, besides other known sesquiterpenes. Syntheses of these internal ethers, as well as the 13-oxa-lactonic analogue, were performed. The antifeedant properties of the internal ethers measured against the storage pests Tribolium confusum, Trogoderma granarium and Sitophylus granarius are reported.
