The metal-free synthesis of 2-aryl-3-arylmethylquinazolin-4(3H)-one is achieved through ionic liquid mediated and I2-promoted tandem oxidative cyclocondensation of isatoic anhydrides with arylmethylamines as the common precursor for the 2-aryl

CuI-catalyzed reactions of N-alkylamidoximes afforded dihydroimidazoles via sp3 C-H amination. On the other hand, the reactions of N-benzoylamidoximes resulted in sp2 C-H amination to form quinazolinones. The reaction mechanisms could be characterized as a redox-neutral radical pathway including a Cu(i)-Cu(ii) redox catalytic cycle. The Royal Society of Chemistry.

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
