Terphenylquinones

Terphenylquinones are fungal dyes from the group of phenyl-substituted p-benzoquinones having the following general structure. "Terphenyl Quinones.svg" "General chemical structure of terphenylquinones" Also derivatives with a central o-benzoquinone structure are known.

Biosynthesis
The biosynthesis of terphenylquinones is carried out by dimerization of substituted oxophenylpropanoic acids (phenylpyruvic acids).

Occurrence
Terphenylquinones are typical constituents of the Boletales.
