With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.19752-84-2,Tetrahydro-2H-pyran-3-ol,as a common compound, the synthetic route is as follows.
STEP 2. DIHYDRO-2H-PYRAN-3(4H)-ONE To a stirred mixture of pyridinium chlorochromate (11.02 g, 51.1 mmol) and 3 A molecular sieves (10.0 g) in DCM (100 mL) was added a solution of tetrahydro-2H-pyran-3-ol (3.48 g, 34.1 mmol) in DCM (100 mL). The reaction mixture was refluxed for 3 h before being cooled to room temperature and partially concentrated in vacuo. The mixture was then diluted with EtOAc and filtered through Celite. The filtrate was concentrated in vacuo and purified by silica gel chromatography to give dihydro-2H-pyran-3(4H)-one.
19752-84-2, As the paragraph descriping shows that 19752-84-2 is playing an increasingly important role.
