This paper reports on the assignment of the 1 H and 13 C NMR spectra of five podocarpene derivatives. Resonance assignments were made on the basis of one‐ and two‐dimensional NMR techniques which included 1 H, 13 C, DEPT and HMQC and also 1D NOE difference spectroscopy. The ratio of the different conformers in the six‐membered C‐ring of the podocarpene system was determined by molecular mechanics calculations and analysis of proton spin–spin coupling constants.
