Several 14‐hydroxy‐14a‐methyl‐( E )‐homoeburnane diastereoisomers have been synthesized and studied by 1 H and 13 C NMR spectroscopy. ID NOE difference experiments, together with proton‐proton correlation and decoupling measurements, have allowed the complete assignment of the 1 H and 13 C NMR spectra. The relative configurations and predominant conformations have been established.
