Category: 453-20-3

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.453-20-3,3-Hydroxytetrahydrofuran,as a common compound, the synthetic route is as follows.,453-20-3

To a solution of tetrahydro-furan-3-ol (9.0 g, 79 mmol) and triethyl amine (20 mL, 176 mmol) in THF (200 mL) was added methanesulfonyl chloride (12.9 g, 1 13 mmol) at 0C. The mixture was stirred overnight and then evaporated to dryness. The residue was extracted with EtOAc (3 x 300 mL) and washed with saturated, aqueous NaHC03. The organic layer was dried over Na2S04 and evaporated to dryness to give methanesulfonic acid tetrahydro-furan-3-yl ester as a yellow viscous liquid (12.4 g, 94%) which was used without further purification.

The synthetic route of 453-20-3 has been constantly updated, and we look forward to future research findings.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.453-20-3,3-Hydroxytetrahydrofuran,as a common compound, the synthetic route is as follows.

3-hydroxytetrahydrofuran (869.00 jiL, 10.56 mmol) was diluted in THF (33.5 mL). Then, the solution was cooled to 0 C and LiHMDS (10.00 mL, 10.56 mmol) was added. After 30 mi 2-fluoro-3-nitropyridine (1.50 g, 10.56 mmol) was quickly added and the reaction mixture was stirred overnight allowing the temperature to reach rt. Thereaction mixture was mixed with another batch (from 100 mg of 2-fluoro-3- nitropyridine) and partitioned between water and EtOAc. The organic layer was separated, dried over MgSO4, filtered and concentrated to afford 2.03 g of intermediate 54 (91% yield) which was directly engaged in the next steps without any further treatment.

As the paragraph descriping shows that 453-20-3 is playing an increasingly important role.

To a 1 L flask, 3-tetrahydrofuran (3-OH-THF, 60.6 g, 0.68 mol, 1 equ.) was charged, followed by DCM (620 mL) and TEMPO(1.08 g, 0.0069 mol, 0.01 equ.) The solution was cooled to -5 ¡ãC. To which TCCA (159.6 g, 0.68 mol, 1 equ.) was added in portions controlling the tern- perature around -5 ¡ãC to 0 ¡ãC. The resulting mixture was allowed to warm to rt and monitored by GC-MS, Reaction was finished in 1 h to give 95percent yield (GC areapercent).

To a solution of 21a (0.6g, 6.81mmol) and TEA (1.05g, 8.17mmol) in THF was added methanesulfonyl chloride (0.86g, 7.50mmol) cooled by ice-bath. The mixture was stirred over weekend and then evaporated. The residue was dissolved in EtOAc and washed with aq. NaHCO3. The organic phase was dried over Na2SO4 and 15 concentrated to provide 21b (1.Ig, 97% yield).

3-Hydroxytetrahydrofuran (83.3 muL, 1.03 mmol) was dissolved in methylene chloride(anhydrous, 2 mL) and cooled to 0 0C followed by the addition of triethylamine (166 muL, 1.2 mmol) and methanesulfonyl chloride (88 muL, 1.14 mmol). The reaction mixture was stirred for 16 h while gradually warming to ambient temperature. The reaction was quenched with water, diluted with methylene chloride (20 mL), and the resulting layers were separated. The organic layer was washed with water (2 x 2 mL) and the combined aqueous phases were extracted with methylene chloride (2 x 3 mL). The combined organic phases were washed with brine (2 x 2 mL), dried over Na2SOzI, filtered, and concentrated. The crude product was used directly in the next step.
