1194-16-7, 2,2-Dimethyltetrahydropyran-4-one is a Tetrahydropyrans compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
To a solution of 2,2-dimethyl tetrehydropyran-4-one (5.0 g, 39.0 mmol) and ethyl diazoacetate (7.1 g, 62.4 mmol) in tetrahydrofuran (100 mL) was added lithium diisopropylamide (2 M in tetrahydrofuran, 35.1 mL, 70.2 mmol) at -78 C under nitrogen. After addition, the reaction mixture was stirred at -78 C for 1H and then quenched by addition of saturated aqueous ammonium chloride (60 mL). The mixture was extracted with ethyl acetate (3 x 100 mL). The combined organic layers were dried over anhydrous sodium sulfate and concentrated to dryness in vacuo. The residue was purified by column chromatography (silica gel, 100-200 mesh, 0 to 20% ethyl acetate in petroleum ether) to afford ethyl 2-diazo-2-(4-hydroxy-2,2-dimethyl-tetrahydropyran-4-yl)acetate (6.0 g, 63.5% yield) as a yellow oil use as is in the next step.
1194-16-7, As the paragraph descriping shows that 1194-16-7 is playing an increasingly important role.
