Chlorinated phenolic sesquiterpenoids from the Arctic fungus Nectria sp. B-13

Abstract Seven chlorinated phenolic sesquiterpenoids, together with one prenylated 2-pyridyl ketone alkaloid ( 9 ) and two monophenols ( 10 and 11 ), were isolated from the fungus Nectria sp. B-13 obtained from an Arctic soil sample. Their chemical structures were elucidated using a combination of spectroscopic data (ESI-MS, 1 H, and 13 C NMR) and comparisons with the published data. This is the first report on the isolation of compounds from pole-derived Nectria sp. B-13. The chemotaxonomic significance of these compounds is discussed.
