N2 - The carbon shifts of the Iboga‐type alkaloids catharanthine, voacangine, coronaridine, ibogaine, dihydrocatharanthine and epiibogamine were recorded and correlated with the conformation of the natural bases. A 13C‐NMR. analysis of heyneanine determined its C(19) configuration and a similar study of epiheyneanine proved its structure.
