624734-17-4, 3-Methoxydihydro-2H-pyran-4(3H)-one is a Tetrahydropyrans compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
624734-17-4, To a solution of the product from Step A (50 mg, 0.39 mmol) in methylene chloride (15 mL) was added Intermediate 4 (128 mg, 0.32 mmol) and N, N-DIISOPROPYLETHYLAMINE (203 uL, 1.17 mmol). After adding molecular sieves (15 mg), sodium triacetoxyborohydride (827 mg, 3. 9 mmol) was added and mixture stirred overnight. The mixture was extracted with methylene chloride, washed with sodium bicarbonate, dried under sodium sulfate and concentrated in vacuo. The crude product was purified on preparation plates (10/89/1, methanol/methylene chloride/ammonium hydroxide). 4 N hydrochloric acid was added and the solution was concentrated in vacuo to yield Example 2 (40 mg, 28%). LC-MS: MW calculated 443.24, found 444.5.
624734-17-4 3-Methoxydihydro-2H-pyran-4(3H)-one 23533610, aTetrahydropyrans compound, is more and more widely used in various fields.
