実験手順
To a stirred solution of the (R)-diastereomer of 4-{3-(4-(R)-Benzyl-2-oxo-oxazolidin-3-yl)-2-[4-(3,3-dimethyl-but-1-enyl)-phenyl)-3-oxo-propyl}-benzoic acid methyl ester (0.43 g, 0.81 mmol) in THF/H2O (20 mL) (3:1) at room temperature were added H2O2 (2.2 mL, 8.1 mmol 35% in H2O) followed by LiOH (40 mg, 1.63 mmol). The reaction mixture was stirred for 3 h, at room temperature, quenched with (0.1 N HCl). The reaction mixture was extracted with ethyl acetate (100 mL) and dried over MgSO4, filtered and concentrated under reduced pressure to afford corresponding acid. The crude product was purified by column chromatography on silica gel, eluting with CH2Cl2/MeOH 2%-15% to afford the title compound (0.4 g, 100%).
