NMR Spectra of Triterpenoids. II. Hopenes and Migrated Hopenes

The 1H- and 13C-NMR signals of eleven triterpenoid hydrocarbons belonging to the hopene and migrated hopene groups were completely assigned by the application of modern NMR techniques, and the conformations are discussed on the basis of Chem3D Plus and MM2 calculations, and nuclear Overhauser effect...

Summary:The 1H- and 13C-NMR signals of eleven triterpenoid hydrocarbons belonging to the hopene and migrated hopene groups were completely assigned by the application of modern NMR techniques, and the conformations are discussed on the basis of Chem3D Plus and MM2 calculations, and nuclear Overhauser effect spectroscopy spectra.
