Structures of zearalenone and zearalanone in solution: A high‐field NMR and molecular modelling study

Abstract The complete 1 H and 13 C NMR spectra of the mycotoxin zearalenone are described. An analysis of all the vicinal proton–proton coupling constants, together with molecular modelling results, leads to a three‐dimensional structure very similar to those observed x‐ray crystallographically for related systems. Analogous data on zearalanone reveal that whereas the overall molecular geometry is similar to that of zearalenone, the alkyl …
