Abstract:
Phenanthridinones are important heterocyclic frameworks present in a variety of complex natural products, pharmaceuticals and displaying wide range of pharmacological actions. Its structural importance has evoked a great deal of interest in the domains of organic synthesis and medicinal chemistry to develop new synthetic methodologies, as well as novel compounds of pharmaceutical interest. This review focuses on the synthesis of phenanthridinone scaffolds by employing aryl-aryl, N-aryl, and biaryl coupling reactions, decarboxylative amidations, and photocatalyzed reactions.

Abstract:
The first Pd-catalyzed cyclization of N-aryl-2-aminopyridines with 2-iodobenzoic acids for the synthesis of phenanthridinones through C–H bond activation under very low catalyst loadings (down to 0.1 mol% Pd) in water is reported. This protocol features a broad substrate scope and provides easy efficient access to various phenanthridinones.

Abstract:
Pd/C was found to be an efficient and convenient metal catalyst for intramolecular C–H arylation reactions in the synthesis of phenanthridinones and dibenzo-α-pyrones. A variety of phenanthridinones and dibenzo-α-pyrones were synthesized under the highly active catalytic system of Pd/C-KOAc-DMA in moderate to excellent yields. The high catalytic activity, high recyclability, low costs, and ease of removal of Pd/C, combined with its commercial availability, render this protocol attractive for both synthetic and industrial applications.

Abstract:
Whilst the cultivation of the Amaryllidaceae genus has primarily been for their ornamental properties, their use in traditional medicine is also well documented. Although over 100 alkaloids from this genus have been isolated, the phenanthridinone analogues narciclasine and pancratistatin isolated from the daffodil bulb, are particularly interesting due to their cytostatic and cytotoxic properties. They have potent and selective anticancer activity which is seemingly unique when compared to currently available chemotherapeutic agents. However, they have yet to be fully exploited as therapeutic

Flow chemistry can be characterized as a continuous chemical reaction system performed in solution in connecting tubing and flow reactors which is efficient. Photochemistry is the chemical reaction initiated by light, and is the result of the absorption of photon by a reagent or starting material. Poly (ADP-ribose) polymerase is a big family of proteins related to cellular repair and death. Phenanthridinones have been shown to exhibit PARP inhibitory potency as competitive inhibitors.
