Diversonol and Blennolide Derivatives from the Endophytic Fungus Microdiplodia sp.: Absolute Configuration of Diversonol
Chemical investigation of the fungal strain Microdiplodia sp. isolated from the shrub Lycium
intricatum led to the isolation of four new compounds: a hexahydroxanthone (2), a 2, 3-
dihydrochroman-4-one (3), a 7-oxoxanthone derivative (4), and a 1, 4-oxazepan-7-one (5).
The relative configurations of the new compounds were determined by intensive NMR
investigations, notably NOESY experiments at different temperatures. The absolute
configurations of the well-known fungal metabolite diversonol (1) and of other xanthone …
