54%; 39% | In methanol; for 2.0h;Cooling with ice; | General procedure: 4-Oxo-1,4-dihydroquinoline-2-carboxylic acid alkyl ester (1,1 mmol), was dissolved in anhydrous methanol (5 mL) (ice bath)and an ethereal solution of diazomethane was added with stirringin small portions until the solution acquired a pale yellow color.After 2 h at room temperature, the reaction mixture was concentratedin vacuo. Products were isolated by chromatographicmethods. Results are presented in Table 2. |

60% | With potassium carbonate; In N,N-dimethyl-formamide; at 220℃; for 0.5h; | General procedure: A mixture of 4-oxo-1,4-dihydroquinoline-2-carboxylic acid alkylester (1, 1 mmol), base (1.3 mmol), the corresponding alkylatingagent (alkyl iodide, 1.5 mmol; others, 1.2 mmol) and anhydrousDMF (5 mL) was stirred at the appropriate temperature andmonitored by TLC (DCM:MeOH 4.7:0.3). After a specified time(Table 2), the mixture was carefully poured into ice-water. Thecompounds obtained were isolated and purified as was indicatedabove. Alkylating agents, bases and solvents are presented inTable 2. |

470 mg | With platinum(IV) oxide; hydrogen; acetic acid; at 20℃; for 12.0h; | General procedure: The 4-hydroxylquinolone (1 equiv.) was dissolved in acetic acid (10.0 niL) under inert conditions, platinum dioxide (5 % weight equiv.) was added and a hydrogen balloon was attached. The reaction was left to proceed for 12 hours. The resulting suspension was filtered through a pad of Celite and washed with ethyl acetate (10.0 mL). The filtrate was concentrated in vacuo to afford a yellow/brown oil. Purification by column chromatography (10 % methanol in chloroform) afforded the title compound. The title compound was synthesised following general procedure B from 2-(methoxycarboxylate)quinolin-4(1H)-one ( 500 mg, 2.5 mmol). The title compound was isolated as colourless solid (470 mg, 2.4 mmol, %). 1H NMR (500 MHz, CDCl3) δ 8.89 (s, 1H), 7.07 (s, 1H), 3.95 (s, 3H), 2.74 (t, J= 6.1 Hz, 2H), 2.56 (t, J= 6.2 Hz, 2H), 1.82 (dt, J = 8.0, 6.1 Hz, 1H), 1.79 - 1.69 (m, 1H); M/Z (ESI+); 208.10 (Found MH+; 208.0977, C11H13NO3 requires 208.0974). |
