Abstract
The 13C NMR spectra of over 24 tetracyclic triterpenoid derivatives have been structurally analyzed. The 13C NMR chemical shifts allow one to probe the steric topology of the rigid steroid skeleton and inductive effects of its substituents.Use of deuterium labeling in chemical shift assignment and B-ring aromatic terpenoids are also featured.
