The synthesis of 2,3-dihydro-4-pyridones and 4-quinolones was realized by visible-light mediated photoredox-catalyzed aerobic dehydrogenation of 4-piperidones and 2,3-dihydro-4-quinolones. This method enables the synthesis of cyclic enaminones in up to 89
Metal-free regioselective formation of C-N and C-O bonds with the utilization of diaryliodonium salts in water: Facile synthesis of: N-Arylquinolones and aryloxyquinolines

Regioselective construction of crucial C-N and C-O bonds leading to N-Arylquinolones and aryloxyquinolines has been accomplished by employing easily accessible diaryliodonium salts and quinolones in water under metal-and ligand-free conditions. This opera

Unsymmetrical cyanine dyes, such as thiazole orange, are useful for the detection of nucleic acids with fluorescence because they dramatically enhance the fluorescence upon binding to nucleic acids. Herein, we synthesized a series of unsymmetrical cyanine
A C-N insertion of β-lactam to benzyne: Unusual formation of acridone
Kim, Jimin,Stoltz, Brian M.
, p. 4994 - 4996 (2012/11/13)
Intermolecular insertion of benzyne into the C-N bond of a β-lactam is described. This σ-insertion is followed by ring expansion that produces dihydroquinolinone, which rapidly reacts with an additional benzyne unit to afford an acridone through intramolecular C-C bond formation to the carbonyl group and rapid elimination of ethylene.
Utilization of aromatic denitrocyclization reaction for the synthesis of 3-unsubstituted 1,4-dihydroquinolin-4-one derivatives
Radl, Stanislav,Obadalova, Iva
, p. 822 - 832 (2007/10/03)
Synthesis of 3-unsubstituted 1-alkyl- and 1-aryl-1,4-dihydroquinolin-4-ones from 2-nitroacetophenone via the corresponding 3-amino-1-(2-nitrophenyl)prop-2- en-1-ones and -but-2-en-1-ones by denitrocyclization reaction is described. The nucleophilic cyclization was achieved either by sodium hydride or potassium carbonate in DMF.
