ChemInform Abstract: A One- and Two-Dimensional 13C and 1H NMR Study of Some Triterpenes of the Hopane, Stictane and Flavicene Groups

Autor: PW Bird, KJ Ronaldson, Alistair L. Wilkins, J. Ralph, J. Bremer, PM Jager, P. T. Holland

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.

Tritium labelling and tritium N.M.R. II. Labelled methyl (Z)-Octadec-9-enoate obtained by partial hydrogenation on Lindlar catalyst, and its reduction to(Z)-Octadec-9-en-1-ol

Autor: AL Odell, RW Martin, KJ Ronaldson, David J. Calvert

Publikováno v: Australian Journal of Chemistry. 35:1615

The selectivity of tritium labelling of double bonds by partial hydrogenation of the acetylenic analogue on Lindlar catalyst is investigated by 3H and 13C n.m.r. Examples of both the secondary isotope effect on chemical shift and the usefulness of 3H

Publikováno v: Australian Journal of Chemistry. 42:243

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
