As the paragraph descriping shows that 89364-31-8 is playing an increasingly important role.
With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.89364-31-8,Tetrahydrofuran-3-carboxylic acid,as a common compound, the synthetic route is as follows.,89364-31-8
To a solution of tetrahydrofuran-3-carboxylic acid (0.247 mL, 2.58 mmol) in THF (13 mL) at 0 ¡ãC was added slowly lithium aluminium hydride (1 .0 M in THF, 5.2 mL, 5.16 mmol), stirred for 10 minutes then allowed to attain room temperature and stirred for a further 3 hours. The reaction mixture was cooled to 0 ¡ãC and diluted with diethyl ether (15 mL), then treated sequentially with water (0.2 mL), NaOH (15percent solution, 0.2 mL) and water (0.6 mL) and stirred for 30 minutes. The white suspension was then treated with sodium sulfate, stirred for a further 20 minutes, filtered over celite, washed with diethyl ether (2x 20 mL) and concentrated in vacuo to yield 224 mg (85percent) of the title compound as a colourless oil which was carried forward to the next stage without further purification. -NMR Spectrum: deltaEta (500 MHz, CDCI3): 3.90-3.84 (2H, m), 3.78-3.73 (1H, m), 3.66-3.63 (2H, m), 3.61-3.57 (1H, m), 2.51-2.46 (1H, m), 2.08-2.01 (1H, m), 1.69-1.62 (1H, m)
