| [Synthesis]
GENERAL STEPS: Under dry conditions, p-toluenesulfonyl chloride (PTSC, 25.0 g) and (R)-oxirane-2-methanol (6.0 mL) were dissolved in anhydrous dichloromethane (DCM, 250 mL). Subsequently, triethylamine (TEA, 36.0 mL) was added slowly and dropwise at 0°C to the reaction mixture. After the reaction was stirred continuously at 0°C for 3 h, the reaction solution was concentrated by rotary evaporator. The crude product was purified by fast column chromatography (eluent: ethyl acetate/petroleum ether) to afford (R)-p-toluenesulfonic acid glycidyl ester (17.6 g) as a white solid. Yield: 85.0%; Melting point: 44-46°C; [α]D25 = +18.3 (c 1.7, acetonitrile). IR (KBr, cm-1): 1598, 1363, 1177, 969, 666, 556. 1H NMR (400 MHz, DMSO-d6) δ: 7.83 (d, J = 8.1 Hz, 2H), 7.52- 7.46 (m, 2H), 4.43 (d, J = 11.6 Hz, 1H), 3.85 (dddd, J = 7.0, 5.7, 3.7, 1.9 Hz, 1H), 3.26-3.17 (m, 1H), 2.78 (t, J = 4.6 Hz, 1H), 2.66-2.58 (m, 1H), 2.42 (s, 3H). esi -MS m/z: 251.2 [M + Na]+. | [References]
