Abstract
Both possible 6-N-oxides of agroclavine (I) and elymoclavine (II) were prepared by hydrogen peroxide oxidation. Their H-1 and C-13 NMR spect ra were assigned and the conformation of the D ring (half-chair) was d etermined. Absolute configuration at 6-N was established by NMR and mo lecular modelling.
