| 摘要: | The new naphthalenone derivatives perenniporides A-D (1-4) were isolated from solid cultures of a fungus Perenniporia sp. inhabiting the larva of Euops chinesis, a phytophagous weevil with high host specificity to the medicinal plant Fallopia japonica. The structures of 1-4 were elucidated primarily by NMR experiments, and 1 was confirmed by X-ray crystallography. The absolute configuration of 1 and 2 was assigned by electronic circular dichroism (ECD) calculations, whereas that of the C-10 tertiary alcohol in 3 was deduced via the CD data of the in situ formed [Rh-2(OCOCF3)(4)] complex and supported by the ECD data Compound 1 showed antifungal activity against five plant pathogens. |
