Methanesulfonic acid 2-oxo-tetrahydro-furan-3S-yl ester Methanesulfonyl chloride (1.67 ml, 21.56 mmol) was added to a stirred solution of (S)-3-hydroxy-2-oxo-tetrahydrofuran (2 g, 19.6 mmol), 4-N,N-dimethylaminopyridine (240 mg, 1.96 mmol) and diisopropylethylamine (3.76 ml, 21.56 mmol) in dry dichloromethane (20 ml), under nitrogen, at -40 C. The mixture was stirred for 30 minutes and then allowed to warm up to room temperature, then it was washed with 2M hydrochloric acid solution (50 ml), dried and evaporated to a solid. The crude product was purified by flash chromatography on silica gel, eluding with ethyl acetate-cyclohexane (1:1). Trituration with diethylether and drying in vacuo afforded the title compound as a crystalline white solid (2.23 g, 63%): mp. 70-75 C.; NMR delta (CDCl3) 5.33 (1H, t, J 8 Hz), 4.53 (1H, dt, J 9 and 2 Hz), 4.34 (1H, dt, J 10 and 6 Hz), 3.28 (3H, s), 2.86-2.72 (1H, m), 2.65-2.47 (1H, m)., 52079-23-9
The synthetic route of 52079-23-9 has been constantly updated, and we look forward to future research findings.
