3-(二甲氨基)-1-(2-硝基苯基)丙-2-烯-1-酮 | (E)-3-(dimethylamino)-1-(2-nitrophenyl)prop-2-en-1-one | 153813-81-1 | C11H12N2O3 | 220.228 |
邻硝基苯乙酮 | 2-Acetylnitrobenzene | 577-59-3 | C8H7NO3 | 165.148 |
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.
