Ligand-Free Pd-Catalyzed and Copper-Assisted C-H Arylation of Quinazolin-4-ones with Aryl Iodides under Microwave Heating
A microwave-assisted method for the palladium-catalyzed direct arylation of quinazolin-4-one has been developed under copper-assistance. This method is applicable to a wide range of aryl iodides and substituted (2H)-quinazolin-4-ones. This protocol provides a simple and efficient way to synthesize biologically relevant 2-arylquinazolin-4-one backbones.
Oxidative radical skeletal rearrangement induced by molecular oxygen: Synthesis of quinazolinones
Oxidative skeletal rearrangement of 5-aryl-4,5-dihydro-1,2,4-oxadiazoles into quinazolinones is induced by molecular oxygen (under a dry air atmosphere) that likely proceeds via transient iminyl radical species. Concise syntheses of biologically active qu
