90.1% | General procedure: 5-Fluoroindole-3-carbaldehyde (0.5 g, 3.07 mmol) and tetrahydrofuran (10 mL) were sequentially added to a 100 mL one-neck round bottom flask, cooled to 0 C, and slowly added NaH (60%, 196 mg, 4.91 mmol) After reacting for 10 minutes,Transfer to room temperature for 1 h, add MeI (0.38 mL, 6.14 mmol),The reaction was carried out at room temperature for 15.5 h, quenched with water (5 mL), and then evaporated to ethyl ether (ethyl acetate) (ethyl acetate (40mL×1)), washed with water (20mL×3), and then ethyl acetate was collected and then purified by column chromatography ( petroleum ether) /ethyl acetate (v/v) = 5/1) to give the title compound as a white solid(0.50 g, 92%). |
Yield | Reaction Conditions | Operation in experiment |
---|---|---|
96% | 5-bromoindole-3-carbaldehyde 2 (10 mmol) was dissolved in acetonitrile and to this powdered NaOH (5 mmol) was added and stirred for 10 min. Methyl iodide (10 mmol) was added dropwise to the reaction mixture. After 3h of stirring at room temperature, the solvent was completely evaporated. It was extracted with ethyl acetate (3x20 ml) and dried over Na2SO4. The combined organic layer was concentrated in vacuo to give a light yellow color solid purified by recrystallization with diethyl ether.

91% | With sodium hydride; In tetrahydrofuran; at 0℃; for 1.83333h; | 5-Bromo-1-methyl-lH-indole-3-carbaldehyde; 5-Bromo-1H-indole-3-carbaldehyde (4.8 mmol, 1076 mg) was dissolved in 15 mL of THF and the solution was cooled to 0 C under N2-athmosphere. Sodium hydride (11.7 mmol, 280 mg) was added carefully in portions and iodomethane (8.1 mmol, 1150 mg) was added. The mixture was stirred at 0 C for 1 h. More iodomethane (8.1 mmol, 1150 mg) was added and the stirring continued for 50 min. The mixture was poured over ice and the resulting slurry was extracted with EtOAc. The organic layer was dried over Na2SO4, filtered and evaporated. This gave 1037 mg (91 %) of the title product. 'H NMR (400 MHz, MeOH-d4) 8 9.82 (s, 1H), 8,29 (m, 1H), 8.06 (s, 1H), 7.43 (m, 2H), 3.89 (s, 3H) |
81% | General procedure: To a suspension of NaH 60% in oil (2.25 equiv.) in dry DMF(0.8 mL/mmol) was added, at 0 C and under nitrogen atmosphere, a solution of indolecarboxaldehyde (1 equiv.) in dry DMF (2.5 mL/mmol). After stirring for 30 min at rt, alkyl halide (1.0e3.0 equiv.)was slowly added. After stirring overnight, the reaction wasquenched by addition of water and the product was extracted withdiethyl ether. The organic layer was dried over MgSO4, filtered offand concentrated under vacuum. The crude product was purifiedby column chromatography on silica gel. |
General procedure: Compounds 7-9 were synthesized from the corresponding compounds 4-6. A solution of compounds 4-6 (60 mmol) in THF (30 mL) were added dropwise to a suspension of NaH (3.60 g, 60% dispersion in mineral oil, 150 mmol) in THF (30 mL) at 0 C. After stirring for 15 min, the heterogeneous mixture was treated with iodomethane (5.04 mL, 79.2 mmol) at room temperature for 1 h. Then the reaction mixture was cooled to 0 C, quenched with saturated NH4Cl (60 mL), and extracted with ether (3 * 50 mL). The organic layers were combined, washed with brine, dried over anhydrous Na2SO4 and concentrated in vacuo to give 1-Methyl-1H-indole-3-carboxaldehyde (7-9), a light brown solid. The crude 7-9 were used in the next step without any further purification. | ||
With sodium hydride; In tetrahydrofuran; at 0 - 20℃; for 24h; | General procedure: The relevant indole-3-carboxaldehyde (2a-c, 10 mmol) in THF(25 mL) was added dropwise to a stirred solution of NaH (25 mmol)in THF (25 mL) at 0 C and CH3I (13.2 mmol) was added after 15 minstirring. The reaction mixturewas moved to room temperature andstirred for further 24 h. Then the solvent was removed in vacuumand the residue was extracted by ethyl acetate. The organic layerwas washed with brine, dried over anhydrous sodium sulfate,filtered and concentrated in vacuum. Recrystallization affordedcompound 3a-c with yields of 93.4-97.5%. |

70% | With water; iodine; oxygen; sodium carbonate; In 1,4-dioxane; at 100℃; under 760.051 Torr; for 60h;Schlenk technique; Sealed tube; | General procedure: Under air, a 20 mL of Schlenk tube equipped with a stir bar was charged with indole 1 (0.2 mmol, 1 equiv),TMEDA (75 muL, 0.5 mmol, 2.5 equiv), Na2CO3 (42.4 mg, 0.4mmol, 2.0 equiv), 1,4-dioxane (0.5 mL) and H2O (100 muL). Then I2 (101.5 mg, 0.4 mmol, 2.0 equiv) was added and the tube was sealed with a rubber plug and charged with O2. The reaction mixture was stirred at 100 C for 36 h in oil bath. After cooling to room temperature, the resultant mixture was evaporated with EtOAc (20 mL) under reduced pressure and the residue was purified by flash column chromatography on a silica gel to give the products. |
