have been determined. The biotransformation of this fungistatic sesquiterpenoid by the plant pathogen Botrytis cinerea gave the 8- and 9-hydroxy derivatives (5 and 3) as the major metabolites and the 6α- and 10β-hydroxy (8 and 7) and 8- and 9-oxo derivatives (6 and 4) as minor metabolites. The structure and stereochemistry of the major compound 3 were established by X-ray crystallography.
