82% | Stage #1: 1-(4-hydroxy-phenyl)-decan-1-one With hydrazine hydrate In diethylene glycol dimethyl ether at 250℃; for 2h; Stage #2: With potassium hydroxide In diethylene glycol dimethyl ether at 190℃; for 4h; | 4-Decylphenyl 2,3-dihydroxybenzoate ( B7 ) Phenol (1.83 g, 19.5 mmol) was added to decanoyl chloride (4.08 g, 21.4 mmol) , stirred at 80 until bubbles were stopped, aluminum trichloride (2.85 g, 21.4 mmol) was added, reflux was performed at 130 for 1 h. When cooled to room temperature, 1 M HCl solution was added to the mixture slowly to quench the reaction, then ethyl acetate was added for dilution, the organic phase was washed with 1 M HCl, saturated NaHCO3 and saturated NaCl successively, and dried with anhydrous Na2SO4. Rotary evaporation was conducted to remove solvent to obtain intermediate (7) as white solid .The product is not purified and characterized, and is directly used for the next step. The intermediate (7) (0.24 g, 0.96 mmol) and hydrazine hydrate (1 ml) were added to diethylene glycol (6 mL), which was stirred at 250 for 2 h and cooled to room temperature. Potassium hydroxide (0.27 g, 4.80 mmol) was added and stirred at 190 for 4 h to remove the excess hydrazine hydrate. When cooled to room temperature, water (27 mL) was added for dilution, and washed twice with ethyl acetate. The water layer was adjusted to acidic with concentrated hydrochloric acid, and extracted three times with ethyl acetate. The combined organic phase was dried with anhydrous Na2SO4 , then filtered and concentrated in vacuo, the crude material was purified by flash chromatography to afford the intermediate (8) as white solid (185 mg, 82%). 1H NMR (400 MHz, DMSO-d6): δ 9.15 (s, 1H), 6.98 (d, J = 8.0 Hz, 2H), 6.68 (d, J = 8.0 Hz, 2H), 2.47 (t, J = 7.4 Hz, 2H), 1.57-1.47 (m, 2H), 1.34-1.22 (m, 14H), 0.88 (t, J = 6.8 Hz, 3H). |

54% | Stage #1: 2,3-Dihydroxybenzoic acid With dicyclohexyl-carbodiimide In acetonitrile at 50℃; for 1h; Inert atmosphere; Stage #2: 4-decylphenol With dmap In acetonitrile at 65℃; | 1 Example 1: Synthesis of Compound I-1,2,3-Dihydroxybenzoic Acid to Ketophyll Ester Under N2, 2,3-dihydroxybenzoic acid (77 mg, 0.5 mmol) was dissolved in 10 ml of dry acetonitrile, N, N'-dicyclohexylcarbodiimide (155 mg, 0.75 mmol) was added, stirred at 50 ° C for 1 h,Followed by addition of 4-chlorophenol (117 mg, 0.5 mmol) and DMAP (6 mg, 0.05 mmol) at 65 C. After stirring overnight,The solvent was evaporated under reduced pressure, and 50 ml of ethyl acetate was added to the residue. The filtrate was filtered with 1 mol / L hydrochloric acid,Saturated aqueous sodium bicarbonate solution, saturated aqueous sodium chloride solution were washed three times, dried over anhydrous sodium sulfate, concentrated under reduced pressure,The residue was chromatographed on silica gel to give 100 mg of white solid in 54% yield; |
52% | Stage #1: 2,3-Dihydroxybenzoic acid With dicyclohexyl-carbodiimide In acetonitrile at 50℃; for 1h; Stage #2: 4-decylphenol With dmap In acetonitrile at 65℃; for 3h; | General esterification procedure for the synthesis of B1-B11 and C1-C4 General procedure: N, N-dicyclohexylcarbodiimide (1.55 g, 7.5 mmol) was added to a solution of 2,3-dihydroxybenzoic acid (0.77 g, 5.0 mmol) in anhydrous CH3CN (20 mL). The reaction mixtures were stirred for 1 h at 50 oC until complete dissolution of the solids was achieved. Next corresponding phenol or alchol (5 mmol) and DMAP (0.06 g, 0.5 mmol) were added to the mixtures and stirred for 3 h at 65 oC, then the mixtures were concentrated under reduce vacuum. The residue was extracted with ethyl acetate three times and then filtered. The filtrate was washed with 5% aqueous citric acid solution, saturated NaHCO3 and brine successively. The organic phase was dried over Na2SO4, filtered, and then concentrated. The crude mixture was purified by column chromatography on silica gel to afford B1-B11 and C1-C4. |
