Tagetolone and tagetenolone: two phytotoxic polyketides from Alternaria tagetica
Abstract
Two new phytotoxic polyketides, tagetolone (1) and tagetenolone (2), in addition to tyrosol and p-hydroxybenzoic acid, have been isolated from the organic crude extract of culture filtrates from the fungal pathogen Alternaria tagetica. Complete characterization of all structures was carried out following a careful analysis of their spectroscopic data (IR, MS, (1)H and (13)C NMR, and 2D NMR experiments).
