実験手順: To a solution of 0.30 g of 2,6-dichloro-4-(3,3-dichloro-2-propenyloxy)phenol, 0.16 g of 3-phenoxy-1-propanol and 0.27 g of triphenylphosphine dissolved in 10 ml of tetrahydrofuran was added dropwise a solution of 0.21 g of diisopropylazodicarboxylate dissolved in 5 ml of tetrahydrofuran, while stirring at room temperature. After stirring at room temperature for 24 hours, the reaction mixture was concentrated to obtain a residue. The residue was subjected to silica gel chromatography, which afforded 0.36 g of 3,5-dichloro-1-(3,3-dichloro-2-propenyloxy)-4-(3-phenoxypropyloxy)benzene (82% yield), nD25.0 1.5762. After stirring at room temperature for 24 hours the reaction mixture was concentrated to obtain a residue

実験手順: To a stirred suspension of 5.7 g (0.15 mole) of lithium aluminum hydride in 350 ml of dry ethyl was added dropwise (30 min) a solution of 25.0 g (0.149 mole) of 3-phenoxypropionic acid (99%, Aldrich Chem. Co.) in 250 ml of dry ethyl ether. The reaction mixture was stirred at ambient temperature for 2 hr and treated successively with 6 ml of water, 18 ml of a 15% sodium hydroxide solution, and 10 ml of water. The reaction mixture was filtered through Celite® and the filtrate was concentrated to a viscous residue. The residue was partitioned between water and ethyl ether (300 ml each). The ethereal layer was washed with two 300 ml portions of water, dried over magnesium sulfate and the solvent was evaporated under reduced pressure to give 16.6 g (73%) of colorless oil.

実験手順: 3-Phenoxypropan-1-ol (3.17 g, 20.86 mmol) was dissolved dichloromethane (25 mL) and pyridinium chlorochromate (6.76 g, 31.28 mmol) was added. The slurry was stirred at room temperature for 1 hour and then filtered through silica gel eluting with an ethyl acetate/hexanes gradient. The desired compound was isolated as a yellow oil (1.1 g). was added filtered through silica gel eluting with an ethyl acetate/hexanes gradient
