Popis: | Chemical shift assignments are reported for some hopane triterpenoids variously oxygenated at C3, C6, C7, C15, C22 and/or C24. Substituent group effects are compared and correlated with a local symmetry axis. Revisions to a recently reported interpretation of the 13C n.m.r. spectrum of 7β-acetoxyhopan-22-ol (1c) are described. |
