With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.110238-91-0,Methyl tetrahydro-2H-pyran-4-carboxylate,as a common compound, the synthetic route is as follows.
A solution of methyl tetrahydro-2H-pyran-4-carboxylate (5 g, 34.6 mmol) in anhydrous diethyl ether was chilled in an ice bath and 1 M LiAlH4 in diethyl ether (52 mL, 51.9 mmol) was added dropwise under an N2 atmosphere. The reaction was allowed to warm to room temperature with stirring overnight. The reaction was quenched by slowly adding 1 N aqueous NaOH (3 mL). The slurry was filtered through a pad of Celite. The Celite pad was rinsed with diethyl ether followed by methanol and the solution was dried in vacuo to yield (tetrahydro-2H- pyran-4-yl)methanol (4 g, 34.6 mmol) as a clear oil. [M+eta] calc’d for C6H]2O2, 117; found, 117., 110238-91-0
As the paragraph descriping shows that 110238-91-0 is playing an increasingly important role.
