With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.453-20-3,3-Hydroxytetrahydrofuran,as a common compound, the synthetic route is as follows.
To a solution of tetrahydrofuran-3-ol (500 mg, 5.68 mmcl) and Et3N (860 mg, 8.52 mmcl) inCH2CI2 (10 mL) at 0 C was added MsCI (842 mg, 7.39 mmol) dropwise. The reaction wasstirred at room temperature for 4 hours. The reaction mixture was diluted with CH2CI2 (150mL), washed with sat. NaHCO3 (50 mL), dried over Na2SO4 and concentrated to give the title compound (700 mg, 74%) as yellow oil.1H NMR (300 MHz, CDCI3): oe 5.36-5.31 (m, IH), 4.06-3.86 (m, 4H), 3.06 (s, 3H), 2.29-2.22 (m, 2H).
453-20-3, As the paragraph descriping shows that 453-20-3 is playing an increasingly important role.
