Sodium metaperiodate (1729 mg, 8.08 mmol) and ruthenium(IV) oxide hydrate (48.8 mg, 0.32 mmol) were added to a solution of benzyl 2-((1R,2S)-2-(hydroxymethyl)cyclopropyl)acetate (712 mg, 3.23 mmol) in acetone (11.5 mL) and water (13 mL) at 0° C., and the mixture was stirred at 0° C. for 2.5 hr. The reaction mixture was poured into water (100 mL), and the mixture was extracted with ethyl acetate (×3). The organic layer was washed with water and brine, and dried over magnesium sulfate, and the solvent was evaporated under reduced pressure to give (1S,2R)-2-(2-(benzyloxy)-2-oxoethyl)cyclopropanecarboxylic acid (690 mg, 2.95 mmol, 91%) as a colorless oil.
