Two novel fomannosane-type sesquiterpenoids from the culture of the basidiomycete Agrocybe salicacola

摘要

Two novel fomannosane-type sesquiterpenoids, agrocybins H (>1) and I (>2), together with a known compound illudosin (>3), were isolated from the culture broth of the mushroom Agrocybe salicacola. Their structures were elucidated by extensive spectroscopic analysis. The relative stereochemistry of >1 was determined by the use of single crystal X-ray crystallographic diffraction.
