Bolineol, a novel co-metabolite of strobilurins A, F and G from Bolinea lutea.

A mycelial co-metabolite of strobilurin A, F and G from Bolinea lutea, which we have named bolineol, has been characterised for the first time. Bolineol (methyl 2-hydroxymethyl-3-methyl-6-phenyl-3Z,5E-hexadienoate) has a similar carbon skeleton to strobilurin A but differs in oxidation level. Its structure has been deduced from its spectral characteristics and those of its acetate. The known compound strobilurin F-1 (methyl 2-methoxymethylene-3-methyl-6-(3'-hydroxyphenyl)-3Z,5E-hexadienoate) has been detected in this organism for the first time and converted into its acetate, a new compound, the structure of which was assigned from its spectral data.
