With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.4295-99-2,4-Cyanotetrahydro-4H-pyran,as a common compound, the synthetic route is as follows.
Reference Example 2: Tetrahydropyran-4-carbaldehyde. To a solution of tetrahydro pyran-4-carbonitrile (1.0 g, 9.0 mmol) in toluene (10 mL) was added diisobutylaluminium hydride solution (DIBAL-H, 10.8 mL, 10.8 mrnol,10 IM in toluene) at -78C. The reaction was stirred at -780C for 1 hour then allowed to warm to r.t. The reaction was quenched with saturated ammonium chloride solution and extracted with ethyl acetate. The combined organics were washed with brine, dried over sodium sulfate, filtered and concentrated under reduced pressure to afford tetrahydropyran-4-carb aldehyde (530 mg, 52 %)., 4295-99-2
4295-99-2 4-Cyanotetrahydro-4H-pyran 11815837, aTetrahydropyrans compound, is more and more widely used in various fields.
