“…Since all compounds share the same DDO backbone, and given that the structure of trigocherrin A (1) has been fully characterized, including its absolute configuration (Allard et al, 2012), only the nature and spatial positions of the substituents on the daphnane core will be discussed in detail. In the NOESY spectra of trigocherrins A and B (1, 2), and trigocherriolide A (7), a set of cross peaks, including a clear correlation between OH-4 and H-8, which indicated a b-orientation of the hydroxy group at C-4, allowed to determine their relative configuration (Figs.…”
