Y. Tezuka et al., STUDIES ON TERPENOIDS AND STEROIDS .23. H-1 AND C-13 NMR SPECTRAL ASSIGNMENTS OF SOME ENE-QUINONEMETHIDE NORTRITERPENOIDS, Phytochemistry, 32(6), 1993, pp. 1531-1534
The H-1 and C-13 NMR spectra of three natural 14(15)-ene-quinonemethid
e nortriterpenoids, balaenonol, balaenol and isobalaendiol have been c
ompletely analysed by the application of two dimensional H-1-H-1 and H
-1-C-13 shift correlation and NOE techniques.
