Exserohilone a novel phytotoxin produced by exserohilum holmii

Journal of Organic Chemistry 50(26): 5631-5633
Exserohilone a novel phytotoxin produced by exserohilum holmii
A novel phytotoxin, exserohilone (1), was isolated from the culture broth of Exserohilum holmii, a pathogenic fungus of the weedy plant Dactyloctenium aegyptium. The structure of exserohilone (1) was elucidated by X-ray diffraction analysis of the bis(p-bromobenzoate) derivative 3. 9,10-Dihydroexserohilone (2) was also isolated, and its structure was determined by spectral methods.
