A new sesquiterpenoid and three other unusual compounds from Xylaria hypoxylon.
A new sesquiterpenoid and three other unusual compounds (1-4) along with four known compounds (5-8) were isolated and identified from the fungus Xylaria hypoxylon. Structures of compounds 1-4 with absolute configurations were elucidated by extensive NMR spectral analyses, X-ray crystallography, experimental ECD spectra...
