14774-37-9, Tetrahydropyran-4-methanol is a Tetrahydropyrans compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
Prepared as described by adaptation of the following literature reference: Radziszewski, J.G. et al. J. Am. Chem. Soc. 1993, 115, 8401 . To 97 g (810 mmol) of (tetrahydro-pyran-4-yl)-methanol in 2- methyltetrahydrofuran (190 mL) are added 165 mL of 50% aq. NaOH solution. To this stirred suspension is added dropwise with cooling a solution of p-toluene-sulfonylchloride (283 g, 1 .46 mol) in 2-methyltetrahydrofuran (280 mL). The reaction is stirred at 30-35 C for 18h. The suspension is poured into a mixture of ice-water (280 mL) and aq. HCI solution (37%, 203 mL). After addition of methylcyclohexane (1 .4 L) and further ice-water (0.2 L), the reaction mixture is stirred for 2 h in an ice-bath. The resulting crystalline precipitate is isolated by filtration and washed with methylcyclohexane (0.5 L) and water (0.5 L). Drying under reduced pressure at 40 C gave 216 g of toluene-4-sulfonic acid tetrahydro-pyran-4-ylmethyl ester. Yield: 99%; ESI-MS: 271 [M+H]+
14774-37-9, As the paragraph descriping shows that 14774-37-9 is playing an increasingly important role.
