title: Sesquiterpenes from cultures of the basidiomycete Conocybe siliginea.
abstract: Six new tremulane sesquiterpenes, conocenol A-D (2-5), conocenolide A (6), and conocenolide B (7), have been isolated from cultures of the basidiomycete Conocybe siliginea. The structures of 2-7 were elucidated by the analysis of spectroscopic data, including heteronuclear multiple-bond correlation, heteronuclear single-quantum coherence, and (1)H,(1)H correlation spectroscopy, and a comparison with known analogues.
