With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.14774-37-9,Tetrahydropyran-4-methanol,as a common compound, the synthetic route is as follows.
To a solution of tetrahydro-2H-pyran-4-ylmethanol (Combi-Blocks, 2.0 g, 17.2 mmol) in 10 mL of of CH2CI2 and 10 mL of of pyridine was added p- toluenesulfonyl chloride (3.5 g, 18.1 mmol) in portions over 15 minutes. The mixture stirred at ambient temperature for 16 hours and was quenched with 10 mL of saturated, aqueous NaHCO3. The layers were separated and the aqueous layer was extracted with three 10 mL portions OfCH2Cl2. The combined organic extracts were dried over anhydrous Na2SO4, filtered and concentrated under reduced pressure to afford the title compound. 1H NMR (300 MHz, dimethylsulfoxide-d6) delta ppm 1.05 – 1.25 (m, 2 H), 1.40 – 1.53 (m, 2 H), 1.73 – 1.94 (m, 1 H), 2.43 (s, 3 H), 3.14 – 3.28 (m, 2 H), 3.71 – 3.84 (m, 2 H), 3.88 (d, J=6.4 Hz, 2 H), 7.48 (d, J=8.5 Hz, 2 H), 7.79 (d, J=8.5 Hz, 2 H); MS (DCI/NH3) m/z 288 (M+NH4)+, 14774-37-9
14774-37-9 Tetrahydropyran-4-methanol 2773573, aTetrahydropyrans compound, is more and more widely used in various fields.
