A palladium catalyzed synthesis of N-H phenanthridinones was developed via C-H arylation. The protocol gives phenanthridinones regioselectively by one-pot reaction without deprotection. It exhibits broad substrate scope and affords targets in up to 95% yields. Importantly, it could be applied for the less reactive o-chlorobenzamides.

An efficient copper-catalyzed synthetic method for the preparation of 2-hydroxybenzamides is described for the first time from 2-chlorobenzamide substrates using copper iodide/1,10-phenanthroline and a base, potassium hydroxide, in neat water. By using this reaction, a series of 2-hydroxybenzamides with functional groups such as fluoro, chloro, iodo, methoxy, amide, and alcohol have been obtained in 33-96% yield. Other aromatic 2-chloroarylamides such as naphthalene, pyridine, and thiophene are found to be equally compatible to the reaction. It is proposed that the reaction proceed via formation of copper-amide complex, which may facilitate the hydroxylation in water. Overall, the first report on copper-catalyzed hydroxylation reaction in water and first catalytic route for the synthesis of 2-hydroxybenzamides is presented. Simple purification procedure and convenience of employing low-cost reagents in neat water make this method practical and economical for the synthesis of 2-hydroxybenzamides.

A range of 14 derivatives of flavone-8-acetic acid (FAA) with a heterocyclic substituent in place of the 2-phenyl group have been prepared and their anti-tumour activity evaluated in vitro against a panel of human and murine tumour cell lines and in vivo against MAC 15A. Some of the compounds, notably 2c,d and s, showed significant in vivo activity and these require further studies in order to evaluate their potential for development.
