The complete assignment of the 'H and 13C NMR spectra of two carbothioamide-substituted meroterpenes is presented. Resonance assignments were achieved by the use of one-and two-dimensional NMR, NOED, selective decoupling measurements and the deuterium isotope effect on the I3C chemical shifts. Six-m
