180 mg | With sulfuric acid; for 17h;Reflux; | (1) A mixture of <strong>[14112-98-2]7-oxooctanoic acid</strong> (158 mg), ethanol (35 mL), and concentrated sulfuric acid (500 μL) was refluxed for 17 hours. The solvent was distilled off under reduced pressure, and then, a saturated aqueous solution of sodium bicarbonate and dichloromethane were added to the residue. The organic layer was separated and dried over anhydrous sodium sulfate, and the solvent was distilled off under reduced pressure to obtain compound (W1) (180 mg). MS (ESI, m/z): 187.2 [M+H]+ |

85% | With iron(III) trifluoromethanesulfonate; In water; at 80℃; for 12h; | 7-Oxooctanoic acid (1d) To a solution of 2-acetylcyclohexanone (1.0 g, 10 mmol) in H2O (10 mL), Fe(OTf)3 (0.25 g, 0.5 mmol) was added. The reaction mixture was vigorously stirred at 80 C for 12 h and the progress of reaction was monitored by TLC. The resulting mixture was warmed to room temperature and extracted with EtOAc (100 mL). The collected organic layer was washed with H2O (100 mL) and brine solution (100 mL).The combined organic layers were dried over MgSO4, filtered, and concentrated under reduced pressure. Purification was performed with flash chromatography on silica gel (petroleum ether: diethyl ether 6:4, Rf = 0.3) to afford keto carboxylic acid 1d as a colorless oil.

80% | With lithium aluminium tetrahydride; In tetrahydrofuran; at 20℃; for 4h; | A solution of <strong>[14112-98-2]7-oxooctanoic acid</strong> (4 g, 25.29 mmol) in THF (10 mL) was added to a stirred solution of LAH in THF (70 mL) under N2 at 0 C The mixture was allowed to warm to rt and stir at rt for 4 h, after which time 10 mL of sat. Na2SO4.10H2O (aq) was added to the solution slowly. White solid crashed out. Additional solid Na2SC>4.10H2O was added and the mixture was filtered through a plug of celite. The filtrate was diluted with EtOAc and washed with brine. The organic layer was separated, dried over Na2SC>4, filtered, and evaporated under vacuum. The residue was purified by silica gel chromatography with (0-40%) EtOAc in hexanes to obtain octane-l,7-diol (2.97 g, 20.31 mmol, 80%).

71% | General procedure: An ozone/oxygen mixture was bubbled througha solution of 7.34 mmol of olefin 5-8 (0.81 g of 5 [11]or 1.00 g of 6, 7, or 8 [12]) in a mixture of 50 mL ofmethylene chloride and 4 mL of acetic acid, cooled to 0(5, 6, 8) or -15C (7), until the initial compound disappeared(TLC). The mixture was purged with argon, and2 mL of 30% aqueous hydrogen peroxide and 0.2 g(1.8 mmol) of selenium dioxide were added withstirring at the same temperature as during the ozonolysis.The mixture was then stirred for at roomtemperature for 48 h and refluxed for 1 h, methylenechloride was evaporated, the residue was dissolved in50 mL of diethyl ether, and a saturated aqueous solution of NaHCO3 was added to pH 8-9. The aqueouslayer was separated, washed with diethyl ether (3×20 mL), acidified with concentrated aqueous HCl topH 4-5, and extracted with diethyl ether (3×50 mL).The combined extracts were washed over MgSO4 andevaporated.7-Oxooctanoic acid (1). Yield 0.59 g (71%),Rf 0.32 (hereinafter, petroleum ether-tert-butyl methylether, 1:1). The IR and 1H NMR spectra were identicalto those reported previously [14]. |
