Cyclization of polyenes xxv. conformational study of cembrene type diterpenes by x-ray analysis
TLDR
An X-ray crystallographic analysis of 15,16-dehydro epimukulol acetate has revealed that the exact stereostructure is indicated in figure 1, which can be depicted on the modified diamond lattice conformation model as shown in figure 2.Abstract:

TL;DR: The structures of (+)-cembrene (1), a macrocyclic diterpene hydrocarbon isolated from pine oleoresins (1, 2), and of the two epimeric cembratrienediols 35 and 36, which were obtained from tobacco (3), were reported in 1962.

Cembrene Diterpenoids: Conformational Studies and Molecular Docking to Tubulin
TL;DR: The macrocyclic cembrenoids are conformationally mobile and numerous low-energy conformations were found and molecular docking reveals that the cEmbrenoids dock into the colchicine binding site of tubulin with comparable docking energies to colchichine.

The conformation of erythronolide, the 14-membered aglycone ring of the erythromycin antibiotics
TL;DR: The solution conformation of erythronolide B and derivatives has been deduced from NMR and CD spectral data as discussed by the authors, which is basically a diamond lattice type in which the ring atoms occupy cyclohexane-like positions but slightly modified to incorporate the lactone and ketone groups and to relieve an unfavorable syn-periplanar interaction.
