反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: Pd(OAc)2 (13.3 mg, 0.06 mmol) was added to a solution of trans-3-(2-chlorophenyl)-2-propen-1-ol (100 mg, 0.59 mmol) in a solution of CH2N2 in Et2O (ca. 0.6 M, 25 mL). The reaction mixture was stirred at room temperature for 1 h. An additional amount of CH2N2 solution in Et2O (25 mL) was added and the mixture was stirred for 1 h. The mixture was filtered through diatomaceous earth and the filtrate was concentrated under reduced pressure. The residue was purified by flash chromatography (CH2Cl2:(CH3)2CO, 95:5) to yield the title compound (85.5 mg, 79% yield). the mixture was stirred for 1 h The mixture was filtered through diatomaceous earth the filtrate was concentrated under reduced pressure The residue was purified by flash chromatography (CH2Cl2:(CH3)2CO, 95:5)

実験手順: A solution of 2-chlorocinnamic acid (5.00 g, 27.4 mmol) in THF (50 mL) was slowly added to a suspension of NaBH4 (1.24 g, 32.9 mmol) in THF (50 mL) at room temperature. The mixture was stirred until evolution of gas ceased. A solution of 12 (3.47 g, 13.7 mmol) in THF (50 mL) was then added and the mixture was stirred at room temperature for 1 h. Aqueous 3 N HCl solution (10 mL) was added carefully and the mixture was extracted with Et2O. The combined organic layers were successively washed with aqueous 1 N NaOH solution and brine, dried (MgSO4), filtered and concentrated under reduced pressure. The residue was purified by flash chromatography (CH2Cl2:(CH3)2CO, 95:5) to yield the title compound (2.86 g, 62% yield). the mixture was stirred at room temperature for 1 h the mixture was extracted with Et2O The combined organic layers were successively washed with aqueous 1 N NaOH solution and brine dried (MgSO4) filtered concentrated under reduced pressure The residue was purified by flash chromatography (CH2Cl2:(CH3)2CO, 95:5)

実験手順: To a solution of (E)-3-(2-chlorophenyl) prop-2-en-1-ol(Preparation example 1, 5.3 g, 31.6 mmole) in THF was added NaH (60% in mineral oil, 0.91 g, 37.7 mmole) and Benzyl bromide (4.12 mL, 34.8 mmole), sequently at 0° C. The reaction mixture was stirred at room temperature for 18 hr. The TLC showed complete consumption of SM. The reaction mixture was quenched with H2O at 0° C. then extracted with EtOAc. The aqueous layer was extracted with EtOAc and separated. The combined organic layer was washed with H2O, then dried over MgSO4 and evaporated under reduced pressure. The crude compound was purified by silica ge column to produce the title compound (4.94 g, 70˜90%). sequently at 0° C consumption of SM The reaction mixture was quenched with H2O at 0° C. then extracted with EtOAc The aqueous layer was extracted with EtOAc separated The combined organic layer was washed with H2O dried over MgSO4 evaporated under reduced pressure The crude compound was purified by silica ge column

実験手順: To a 250 ml round-bottomed flask, (E)-3-(2-chlorophenyl)prop-2-en-1-ol (2.96 g, 17.5 mmol, Preparation example 1) and Dichloromethane (17.5 ml) were added and the reaction mixture was cooled to 0° C. Diisopropylethylamine (6.1 ml, 35.1 mmol) was added and stirred at 0° C. Methyl chloromethyl ether (2.77 ml, 35.1 mmol) was added dropwise and stirred for overnight. The reaction mixture was quenched with 1N NaOH solution, extracted by dichloromethane. The combined organic extracts were dried over anhydrous magnesium sulfate (MgSO4), filtered and concentrated under vacuum. The crude compound was purified by a silica gel column to produce the title compound (3.43 g, 85˜95%). stirred for overnight The reaction mixture was quenched with 1N NaOH solution extracted by dichloromethane The combined organic extracts were dried over anhydrous magnesium sulfate (MgSO4) filtered concentrated under vacuum The crude compound was purified by a silica gel column
