Abstract
Cavoxin (1) was isolated as the main phytotoxin produced by Phoma cava Schulzer, a toxigenic fungus isolated from Castanea spp. Its structure was determined by 1D NMR and MS in 1985 along with that of the corresponding chroman-4-one cavoxone (2), an artifact formed by acid treatment of 1. Since that time cavoxin was shown to be phytotoxic, antifungal, antifeedant, herbicidal, and antirust with potential application in agriculture and medicine. During a study aimed at improving cavoxin's production by P. cava, single crystals for X-ray diffractometric analysis were obtained. The X-ray crystallography characterization confirmed only in part the structure proposed for cavoxin (1), revealing a different substitution pattern on the aromatic ring, as depicted in the revised structure 3.
