2081-44-9, Tetrahydro-2H-pyran-4-ol is a Tetrahydropyrans compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
Paratoluenesulfonyl chloride (300.0 g, 1.58 mol) is added to a solution of compound 21 (100.0 g, 0.98 mol) in 800.0 mL of pyridine at 0C. After stirring the reaction mixture at room temperature for 14 hours, it is pored into an ice solution of 6N HCl. Some precipitate is formed that is filtered and triturated with hexanes. After drying under vacuum the crude compound 22 is used without further purification in the next step. 1H NMR (400 MHz, chloroform-d) delta ppm 1.70-1.89 (4H, m), 2.45 (3H, s), 3.44-3.50 (2H, m), 3.86 (2H, p), 4.70 (1H, m), 7.33 (2H, d, 8.4 Hz), 7.79 (2H, d, 8.0 Hz).
2081-44-9, As the paragraph descriping shows that 2081-44-9 is playing an increasingly important role.
