✦ Synopsis

The 20.15 MHz 13C NMR spectra of five 3,6,9-trioxanthracenes and four 3,6-dioxa-9-thianthracenes have been assigned using a variety of one-dimensional techniques. These include spin-echo multiplicity sorting (SEFT), long-range heteronuclear coupling constant determination via gated decoupling and selective heteronuclear 13C{ 'H} NOE difference spectroscopy. The axial position of substituents on C-10 has been demonstrated.

## Abstract The ^1^H and ^13^C NMR data for 3‐azabicyclo[3.3.1]nonanes with OH and OMe substituents at C‐6 and C‐9 were measured using 1D (DEPT) and 2D (COSY, HSQC, HMBC, NOESY) experiments. Comparison of this NMR data illustrates the effects of stereochemistry and substitution at these positions.

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
