2-(2-乙基苯基)乙烷-1-醇

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: Into a 50-mL round-bottom flask was placed ether (10 mL), CH3CN (5 mL) and 2-(2-ethylphenyl)ethan-1-ol (900 mg, 5.99 mmol, 1.00 equiv). Then imidazole (570 mg, 8.38 mmol, 1.40 equiv), PPh3 (2.20 g, 8.39 mmol, 1.40 equiv) and I2 (1.98 g, 7.80 mmol, 1.30 equiv) were added at 0° C. The resulting solution was stirred for 6 h at room temperature. The reaction was then quenched by the addition of 10 mL of saturated Na2SO3 solution. The resulting solution was extracted with 3×50 mL of ethyl acetate and the organic layers combined, dried over Na2SO4 and concentrated under vacuum. The residue was applied onto a silica gel column with ethyl acetate/petroleum ether (1:20). Purification afforded 1.16 g (74%) of 1-ethyl-2-(2-iodoethyl)benzene as a colorless oil. Into a 50-mL round-bottom flask was placed The reaction was then quenched by the addition of 10 mL of saturated Na2SO3 solution The resulting solution was extracted with 3×50 mL of ethyl acetate dried over Na2SO4 concentrated under vacuum Purification

反应条件: temp:0.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: Into a 250-mL round-bottom flask protected by N2 was placed tetrahydrofuran (100 mL), Mg (1.0 g, 41.67 mmol, 2.14 equiv) and I2 (0.010 g). Then a solution of 1-bromo-2-ethylbenzene (3.6 g, 19.45 mmol, 1.00 equiv) in THF (15 mL) was added dropwise. The resulting mixture was heated to reflux for 1 h. Then it was cooled to 0° C. and oxirane (50 mL) was added. The resulting solution was stirred at room temperature overnight. The reaction was then quenched by the addition of 20 mL of NH4Cl (aq.). The resulting solution was extracted with 3×50 mL of ethyl acetate and the organic layers combined and concentrated under vacuum. The residue was applied onto a silica gel column with ethyl acetate/petroleum ether (1:5). Purification afforded 1.83 g (63%) of 2-(2-ethylphenyl)ethan-1-ol as a colorless oil. The resulting mixture was heated to reflux for 1 h The reaction was then quenched by the addition of 20 mL of NH4Cl (aq.) The resulting solution was extracted with 3×50 mL of ethyl acetate concentrated under vacuum Purification
