Over the past half a century, the structure and configuration of the rotenoids, a group of natural products showing multiple promising bioactivities, have been established by interpretation of their NMR and electronic circular dichroism spectra and confirmed by analysis of single-crystal X-ray diffraction data. The chemical shift of the H-6' <sup>1</sup>H NMR resonance has been found to be an indicator of either a <i>cis</i> or <i>trans</i> C/D ring system. In the present study, four structures ...[more]
