Kurzfassung:
Two stereoisomers of ascolactone ( A , B ), natural products with two asymmetric carbon atoms, are isolated from the marine‐derived fungus Ascochyta salicorniae . Although these compounds show virtually opposite CD spectra and [α] D , 1 H‐ and 13 C‐NMR data exclude the presence of enantiomers and suggest ascolactone A and B to be epimeric lactones. By comparing the experimental CD spectra with those calculated employing time‐dependent density functional theory (TDDFT), we elucidate the configuration at one of the asymmetric carbon atoms.
