反应详情

Into a 100-mL 3-neck round-bottom flask, was placed a solution of (4-methyltetrahydro-2H-pyran-4-yl)methanol (compound 188.2, 300 mg, 2.30 mmol) in dichloromethane (15 mL). Dess-Martin reagent (1.17 g, 2.76 mmol) was added to the reaction. The reaction mixture was stirred for 2 h at room temperature, then quenched with 15 mL of water. The aqueous phase was extracted with 20 mL of dichloromethane. The combined organic layers were dried over anhydrous sodium sulfate and concentrated under reduced pressure. This resulted in 200 mg (68%) of the title compound as a yellow oil.
