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
To a room temperature mixture of NaH (60% in hexane, 10.0 g, 250 mmol) in THF (300 mL) were added tetrahydropyran-4-one 1 (10.0 g, 100 mmol) and dimethylcarbonate (21 mL, 250 mmol). Then the mixture was heated to 45C overnight. The final mixture was poured into 0.0 IN HC1 and Et20, filtered over celite, the separated organic layer was dried over anhydrous sodium sulfate and the residue was purified over silica gel (petroleum ether/ethyl acetate =50: 1) to give the desired product 2 (7.8 g, 49% yield). 1H-NMR (300 MHz, CDCls) delta: 4.23 (m, 1H), 3.84 (t, 2H), 3.77 (m, 2H), 3.75 (s, 3H), 2.39 (m, 2H)., 29943-42-8
The synthetic route of 29943-42-8 has been constantly updated, and we look forward to future research findings.
