29943-42-8, Dihydro-2H-pyran-4(3H)-one is a Tetrahydropyrans compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
Reference Example 17 Tetrahydro-2H-pyran-4-ylamine hydrochloride To a solution of tetrahydro-4H-pyran-4-one (4.30 g, 43.0 mmol) in methanol (112 ml) was added an aqueous solution (12.5 ml) of ammonium formate (25 g, 400 mmol). Insolubles were completely dissolved and then 10percent palladium carbon (5.1 g) was added thereto, which was stirred at room temperature overnight. After the insolubles were filtrated off to obtain a filtrate, which was concentrated, and to the residue was added ethanol (100 ml) and concentrated hydrochloric acid (7.5 ml). The solvent was distilled off under reduced pressure to give an objective product, which was collected by filtration and washed with ether. 1H-NMR (DMSO-d6) delta: 1.54-1.74 (2H, m), 1.82-1.98 (2H, m), 3.27-3.38 (3H, m), 3.87-3.94 (2H, m), 9.05 (3H, bs). IR (KBr) cm-1; 2966, 1377, 1163, 1088, 1015, 986, 862.
29943-42-8, The synthetic route of 29943-42-8 has been constantly updated, and we look forward to future research findings.
