29943-42-8, Dihydro-2H-pyran-4(3H)-one is a Tetrahydropyrans compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
To 75 g (0.75 mol) of tetrahydropyran-4-one in THF (150 mL) is added a suspension of 28.4 g (0.75 mol) LiAlH4 in THF (600 mL) under nitrogen atmosphere maintaining the temperature below 30 C. with the aid of an ice-bath. Then the reaction is allowed to warm to RT and stirred for 5 h. The reaction is quenched by addition of sat. aq. NH4Cl solution until effervescence ceased. The resulting precipitate is removed by filtration through Celite and washed with THF (150 mL). The filtrate is concentrated under reduced pressure to afford 71.1 g of tetrahydropyran-4-ol. Yield: 92%.
29943-42-8, The synthetic route of 29943-42-8 has been constantly updated, and we look forward to future research findings.
