Although phenanthridine was discovered in the late nineteenth century1, 2 neither the parent base nor its derivatives attracted attention until useful therapeutic activity was established in certain quaternary phenanthridinium compounds.3 A substantial number of substituted phenanthridines (and many phenanthridinium salts) have now been described and lists of compounds appearing in the literature from 1884 until 1955 are available.4, 6 Phenanthridines have attracted surprisingly little systematic attention, although the system is of considerable theoretical interest and, with its nine nonequivalent carbon atoms, may be expected to provide a rigorous test of molecular orbital reactivity correlations. Naturally occurring derivatives include several Amaryllidaceae and Papaveraceae alkaloids, notably, lycorine, haemanthamine, and chelidonine the chemistry of the phenanthridine alkaloids has been reviewed.6...
