127956-11-0, Methyl 4-oxotetrahydro-2H-pyran-3-carboxylate is a Tetrahydropyrans compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
Example 9 2-Phenyl-3,5,7,8-tetrahydropyrano[4,3-d]pyrimidin-4-one A solution of methyl 4-oxotetrahydropyrane-3-carboxylate (112 mg) and benzamidine hydrochloride (470 mg) in methanol (2 ml) was added with potassium carbonate (100 mg) and heated under reflux for 3 hours. The reaction mixture was cooled, then poured into water, and extracted with dichloromethane. The organic layer was dried over anhydrous magnesium sulfate and then evaporated under reduced pressure, and the residue was purified by silica gel column chromatography to obtain the above-titled product (90 mg). 1H-NMR (CDCl3) delta: 2.83 (2H, t, J=5.6Hz), 4.02(2H, t, J=5.6Hz), 4.67 (2H, s), 7.50-7.60 (3H, m), 8.08-8.12(2H, m). Mass (EI, m/z): 228(M+)., 127956-11-0
As the paragraph descriping shows that 127956-11-0 is playing an increasingly important role.
