Phenanthridine- and phenanthridone-type amaryllidaceae alkaloids

Amaryllidaceae alkaloids compounds based on the phenanthridine or the phenanthridone skeleton. Phenanthridone-type alkaloids have the highest oxygenated C ring in all Amaryllidaceae alkaloids, and they always show an amide group in ring B. On the contrary, alkaloids of the phenanthridine type often show completely aromatic ring system, occasionally with a methylation quaternary nitrogen atom.
