Terphenylquinones

Terphenylquinones are fungal dyes from the group of phenyl-substituted p-benzoquinones having the following general structure.[1]

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.
