80% | With ethanol; potassium hydroxide; at 0 - 20℃; for 19.0333h; | To an ice cooled solution of (2R ,3R)-diethyl 2,3 -epoxy succinate (250 mg, 1.33 mmol, Sigma-Aldrich Corporation) in ethanol (3 mL) was added dropwise a solution of potassium hydroxide (89 mg, 1.594 mmol, VWR International, LLC) in ethanol (2.0 mL) over 2 minutes. After this addition the reaction mixture was allowed to stir at 0 C for 3 h. The resulting reaction mixture became a gel-like mixture. The cooling bath was then removed and the reaction mixture was stirred for further 16 h at room temperature. Afterwards the ethanol was removed in vacuo leaving an off white solid. This salt was then taken up with 10 mL of water and washed three times with dichloride methane. The aqueous phase was acidified by addition of 2 M HC1 to pH 3 and extracted with ethyl acetate (10 mL x 3). The combined organic phase was dried over MgSCri, filtered, and concentrated in vacuo. After drying the pure product (2R,3R)-3- (ethoxycarbonyl)oxirane-2-carboxylic acid (170 mg, 1.06 mmol, 80 % yield) was obtained as a colorless oil. 1H NMR (400 MHz, CDC13) d 8.41-9.03 (brs, 1H), 4.29 (ttd, J= 3.6, 7.1, 10.7 Hz, 2H), 3.72-3.73 (m, 1H), 3.70-3.72 (m, 1H), 1.33 (t, J=1.2 Hz, 3H).
