Secondary mould metabolites. Part 41. Structure and biosynthesis of Cercospora beticola toxin (CBT)

Abstract

The structure of Cercospora beticola toxin (CBT)1, a phytotoxic metabolite, was elucidated on the basis of mass, 1H NMR, 13C NMR and 2D NMR (13C, 13C COSY and 1H, 1H ROESY) spectra and from biosynthetic evidence obtained from incorporation of [1-13C]acetate and [1,2-13C] acetate. The product is a 2:2 complex with Mg of a compound derived from the coupling of two octaketide-derived reduced anthraquinone and xanthone moieties.
