Publikováno v: ChemInform. 20

By use of 2D NMR a complete assignment of the proton resonances of (I) and (II) and the characterization of the new hydroxystictanolactone (III) (from lichen Pseudocyphellaria coronata) are achieved.

The phase sensitive two-dimensional (2D) 13C-1H heteronuclear correlated and double quantum filtered cosy n.m.r. spectra of the triterpenes 7β-acetoxyhopan-22-ol and 2 α,3 β,22 α- triacetoxystictane have been recorded at a resolution sufficient f

A 13C N.M.R. Study of Some Oxygenated Hopane Triterpenes

Autor: AL Wilkins, PM Jager, KJ Ronaldson, PW Bird

Publikováno v: Australian Journal of Chemistry. 40:1713

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 interpre
