摘要
Three new compounds, ascotrichols A-B (1-2) and ascotrichrone A (3), along with two known isocoumarin derivatives (4-5), were isolated from the solid culture of a sea mud-derived fungus, Ascotricha sp. ZJ-M-5 on rice media. The structures were elucidated by extensive spectroscopic analyses, including 1D and 2D NMR data, and the absolute configurations were determined by electronic circular dichroism and biogenetic correlation.
