by the plantpathogenicfungus Leptosphaeria maculans led to the isolation and structure elucidation of eight new metabolites, the leptomaculins and deacetylleptomaculins A-E. The chemical structures and absolute stereochemistry of the new metabolites were deduced by detailed analysis of 1D and 2D NMR spectroscopic data and chemical degradation of the toxin sirodesmin PL. Leptomaculins A and B are the
