Structure of a fungal metabolite of the phytoalexin wyerone acid fromVicia faba L.
Abstract
The isolation and identification of the major detoxification product of wyerone acid (a phytoalexin fromVicia faba L.), produced byBotrytis fabae, are described. The compound has been shown to be 3-[5-(1-hydroxy-cis-hept-4-enyl)-2-furyl]-trans-prop-2-enoic acid, by total synthesis of the methyl ester.
