23462-75-1, Dihydro-2H-pyran-3(4H)-one is a Tetrahydropyrans compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
Step 1 Methylmaganesium bromide (1.831 mL, 5.49 mmol) was added dropwise via syringe to a solution of dihydro-2H-pyran-3(4H)-one (500 mg, 4.99 mmol) in Diethyl ether (50 mL) at -20 C. and stirred at this temp for 1 hr before warming up to RT. The reaction was quenched with sat. ammonium chloride and extracted with ether. The organic layer was washed with brine, collected, dried over MgSO4, filtered and partially evaporated to give the crude product 3-methyltetrahydro-2H-pyran-3-ol (480 mg, 83% yield) as an oil. 1H NMR (400 MHz, CHLOROFORM-d) delta 3.90-3.81 (m, 1H), 3.55-3.50 (m, 1H), 3.40 (td, J=11.3, 2.8 Hz, 1H), 3.31 (d, J=11.3 Hz, 1H), 2.16 (br. s., 1H), 1.94-1.81 (m, 1H), 1.78-1.69 (m, 1H), 1.59-1.47 (m, 2H), 1.18-1.11 (m, 3H)., 23462-75-1
23462-75-1 Dihydro-2H-pyran-3(4H)-one 90109, aTetrahydropyrans compound, is more and more widely used in various fields.
