Abstract

The stereochemistry previously proposed for herbamine (V) and herbadine (II) as C2-βH has been reconsidered on the basis of a comparative study of the13C NMR of these compounds and of vincamajine, quebrachidine, ajmaline, vincamajoreine, and majoridine, and it has been established unambiguously that herbamine and herbadine belong to the dihydroindole alkaloids with C2-αH, herbamine being C3-hydroxyvincamajine, and herbadine C6-hydroxyquebrachidine.
