Four new metabolites, neovasipyrones A and B and neovasifuranones A and B, were isolated from the phytopathogenic fungus Neocosmospora vasinfecta NHL2298, and their structures were elucidated by spectroscopic methods. The absolute stereochemistry of the neovasipyrones was established by X-ray analysis and chemical reactions.
