Abstract
The γ-lactone obtained from acid treatment of dihydroisopimaric acid was found to have a cis-A/B ring fusion. This structure revision was based on 13C nmr chemical shift data and spin–lattice relaxation time (T1) measurements. Using the same methods, the δ-lactone derived from the same acid was shown to have the previously proposed structure.
