The structure of the dimeric eudesmanolide hydroxy‐bis‐dihydrofarinosin (1) from Encelia farinosa followed after contrasting their 1H and 13C NMR spectra with those of encelin (6), hydroxy‐bis‐dihydroencelin (3), and farinosin (4). Structure 1 was verified by single‐crystal X‐ray diffraction analysis, which further provided the stereochemistry of the hydroxy group at C‐4. Comparison of the experimental vibrational circular dichroism spectrum of its derived diacetate 2 with that calculated by… Expand
