Intramolecular oxidative C?H amination of 2-aminobenzophenones was achieved in the presence of potassium tert-butoxide and dimethyl sulfoxide. A series of functionalized acridones were prepared in moderate to excellent yields in a mild, efficient, and transition-metal-free manner. (Figure presented.).

A novel method has been developed for the synthesis of substituted N-methylacridones from 2-(N-methyl-N-phenylamino)benzaldehydes via dehydrogenative cyclization. This transformation involves two primary processes: the aldehyde first coordinates with Sc(OTf)3 and induces the aromatic electrophilic substitution (SEAr) reaction to form the active intermediate N-methyl-acridin-9-ol, which is then quickly oxidized in situ to afford the acridones. Furthermore, the procedure involved is both environmental friendly and atom efficient; H2O is the only byproduct in this reaction.
Copper-catalyzed intramolecular oxidative C-H functionalization and C-N formation of 2-aminobenzophenones: Unusual pseudo-1,2-shift of the substituent on the aryl ring

A good move: A copper-catalyzed intramolecular oxidative C-H functionalization of 2-aminobenzophenone affords two regioisomeric acridones (see scheme). The reaction involves an unusual pseudo-1,2-migration of R 2 group(s) on the arene ring (bpy=2,2-bipyridine, DMAc=dimethylacetimide). Copyright
