85% | With iodine; In dimethyl sulfoxide; at 80℃; for 12h; | General procedure: A mixture of 2 (1 mmol) and iodine (1.5 mmol) inDMSO was warmed at 80°C in an oil bath for 12 hours. On completion of the reaction, the reaction mixture was poured onto saturated solution of sodium thiosulfate. The precipitated solid was collected and the desired product was purified by column chromatography using silica gel (60x120 mesh) with increasing percentage of ethyl acetate in hexaneas eluting solvent. The physical data of compounds are provided below. |

98% | With zirconyl(IV) nitrate hydrate; In ethanol; water; at 50℃; for 3h;Green chemistry;Catalytic behavior; | General procedure: A mixture of the appropriate 2-aminochalcone (1 mmol), EtOH(2 mL), H2O (2 mL), and ZrO(NO3)2·nH2O (46 mg, 20 molpercent) washeated with stirring at 50 °C while the progress of the reactionwas monitored by TLC. The reaction was then quenched withH2O (5 mL), and the mixture was extracted with Et2O (3 × 10mL). The combined organic extracts were washed with brine (5mL) then dried (Na2SO4), filtered, and concentrated underreduced pressure. The crude product was purified by columnchromatography [silica gel, hexane?EtOAc (10:1)]. 2-Phenyl-2,3-dihydroquinolin-4(1H)-one (Table 2, Entry1)5b,6b,11Off-white solid; yield: 218 mg (98percent); mp 153?155 °C.

56% | With hydrogenchloride; In water; for 12h;Reflux; | General procedure: A mixture of 1 (1 mmol) and 5percent HCl (10 ml) was refluxed for 12 hours. The reaction mixture was kept at room temperature and then basified with NH4OH. The precipitated solid was filtered sand recrystallized from ethanol. The physical data for the characterstic compound is shown below |
4.75 g | With hydrogenchloride; In ethanol; water; for 8h;Reflux; | 7.9 g (0.03 mol) of (E)-N-[2-(3-phenylacryloyl)phenyl]acetamide (C1) was dissolved in 80 ml of ethanol. Add 40 ml of 5percent hydrochloric acid and reflux for 8 h. The reaction solution was poured into 200 ml of ice water, and the pH was adjusted to 9 with aqueous ammonia to precipitate a large amount of white solid. Filtering, ethanol recrystallization, 2-phenyl-2,3-dihydro-4(1H)-quinolinone (D1) is obtained as a white solid. The yield is 4.75g, the yield is 71.1percent |
