实验步骤: To 3-(tetrahydrofuran-2-yl)propan-1-ol (3.90 g, 30.0 mmol) was added dichlorosulfoxide (15 mL) dropwise under N2 and the mixture was refluxed for 3.5 h. It was then cooled to rt and concentrated in vacuo. To the residue was added water (30 mL) and the resulting mixture was extracted with DCM (30 mL×4). The combined organic layers were washed with brine (40 mL×2), dried over anhydrous Na2SO4 and concentrated in vacuo to give the title compound as yellow liquid, which was used for next step without further purification. the mixture was refluxed for 3.5 h concentrated in vacuo To the residue was added water (30 mL) the resulting mixture was extracted with DCM (30 mL×4) The combined organic layers were washed with brine (40 mL×2) dried over anhydrous Na2SO4 concentrated in vacuo

实验步骤: To a solution of 3-(tetrahydrofuran-2-yl)propanoic acid (11.5 g, 80.0 mmol) in anhydrous THF (200 mL) was added borane (160 mL, 160 mmol, 1 mol/L in THF) dropwise under N2 and the mixture was stirred at rt overnight. The reaction mixture was quenched with MeOH and concentrated in vacuo to give the title compound, which was used for next step without further purification. The reaction mixture was quenched with MeOH concentrated in vacuo
