摘要
Eight closely biogenetically-related aromadendrane-type sesquiterpenoids, six of them new, scedogiines A-F (1-3, 6-8), together with a new polyketide scedogiine G (9) were discovered from the culture broth of the marine-derived fungus Scedosporium dehoogii F41-4 by NMR-guided isolation. Their structures were determined from extensive NMR and HR-ESI-MS data. The absolute configurations of the new sesquiterpenoids were elucidated by ECD calculation. Plausible biogenetic pathways of the aromadendrane analogues were postulated.
