((2R,3R,4R)-3-(benzoyloxy)-4-fluoro-4-methyl-5-oxotetrahydrofuran-2-yl)methyl benzoate is an impurity of Sofosbuvir. Sofosbuvir is a NS5B inhibtor used for the treatment of hepatitis C. It is only recommended with some combination of ribavirin, peginterferon-alfa, simeprevir, ledipasvir or daclatasvir.
| [Synthesis]
(3R,4R,5R)-3-fluoro-4-hydroxy-5-(hydroxymethyl)-3-methyldihydrofuran-2(3H)-one (60 mg, 0.16 mmol) was dissolved in anhydrous pyridine (1 mL) and benzoyl chloride (0.3 mL) was added slowly. The reaction mixture was stirred at room temperature for 20 min, then water (1 mL) was added and stirring was continued for 20 min. The reaction solution was diluted with ethyl acetate (5 mL) and washed sequentially with water (2 mL) and 1M HCl (2 mL x 3). The organic phase was dried with anhydrous sodium sulfate, filtered and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (eluent: hexane/ethyl acetate=10:1) to afford ((2R,3R,4R)-3-(benzyloxy)-4-fluoro-4-methyl-5-oxo-tetrahydrofuran-2-yl)methyl benzoate (118 mg, 87% yield) as a white solid.1H NMR (CDCl3) δ (ppm): 8.08 (m, 2H. Ar-H), 7.99 (m, 2H, Ar-H), 7.63 (m, 1H, Ar-H), 7.58 (m, 1H, Ar-H), 7.49 (m, 2H, Ar-H), 7.43 (m, 2H, Ar-H), 5.51 (dd, 1H, J=7.2,17.6Hz, H-3), 5.00 (m, 1H, H-4). 4.78 (dd, 1H, J=3.6,12.8Hz, H-5), 4.59 (dd, 1H, J=5.2,12.8Hz, H-5'), 1.75 (d, 3H, J=23.6Hz, CH3-2). | [References]
