4295-99-2, 4-Cyanotetrahydro-4H-pyran is a Tetrahydropyrans compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

4-(3-Chloropropyl)-tetrahydro-2H-pyran-4-carbonitrile. To a stirred solution of 1 M LiHMDS (25 mL, 25 mmol) in THF (10 mL) at -78 C. was added dropwise a solution of tetrahydro-2H-pyran-4-carbonitrile (2.23 g, 20 mmol) in THF (15 mL) over 10 minutes. After 40 min, 1-chloro-3-iodopropane (2.7 mL, 25 mmol) was added at once, stirred at -78 C. for 1 h and 4 h room temperature. Then the reaction mixture was diluted with ether (100 mL), washed with water (20 mL) and brine (20 mL), dried (Na2SO4), filtered and concentrated to give yellow oil which was purified by flash column chromatography using 10-30% EtOAc/Hexanes to afford the title compound as a colorless liquid (3.74 g, 99%). 1H NMR (500 MHz, CDCl3) delta: 3.97 (2H, dd, J=11.3, 3.7 Hz), 3.71 (2H, td, J=12.2, 1.8 Hz), 3.61 (2H, t, J=6.3 Hz), 2.05-1.98 (2H, m), 1.88 (2H, dd, J=13.4, 1.8 Hz), 1.77-1.74 (2H, m), 1.65-1.59 (2H, m)., 4295-99-2

The synthetic route of 4295-99-2 has been constantly updated, and we look forward to future research findings.
