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.
Step 1 a Synthesis of Tetrahydro-2H-pyran-4-yl)methyl 4-methylbenzenesulfonate To a stirred solution of (tetrahydro-2H-pyran-4-yl)methanol (300 mg, 2.58 mM) in DCM (5 ml), triethyl amine (784 mg, 7.75 mM) was added. The reaction mixture was stirred for 5 min at 0 QC followed by the addition of 4-methylbenzene-1 -sulfonyl chloride (542 mg, 2.84 mM). The reaction mixture was further stirred for 2h. RM, concentrated and purified by column chromatography to afford the title compound tetrahydro-2H-pyran-4-yl)methyl 4-methylbenzenesulfonate (634 mg). Yield: 91 %; 1 H NMR (CDCI3, 300 MHz): delta 7.81 (d, J=8.1 Hz, 2H), 7.38 (d, J=8.1 Hz, 2H), 3.97-3.86 (m, 4H), 3.36 (t, J=6.5 Hz, 2H), 2.47 (s, 3H), 1 .97-1 .94 (m, 1 H), 1 .62 (d, J=12 Hz, 2H), 1 .35-1 .23 (m, 2H), MS: m/z 293 (M+Na)., 14774-37-9
14774-37-9 Tetrahydropyran-4-methanol 2773573, aTetrahydropyrans compound, is more and more widely used in various fields.
