Participants

Reaction Conditions

Reaction Steps

0.71 g of azetidine-2-one and 0.82 g of anhydrous sodium acetate were suspended in 20 ml of acetonitrile and cooled to -5°, to which 10 ml of acetonitrile containing 0.26 g of ruthenium trichloride.3H2O was added. 3.8 ml of acetic acid containing 40% peracetic acid was carefully dropped thereto so as to maintain the temperature not higher than 0° C., then continuously stirred at 0° C. for 30 minutes. The solvent was distilled off under reduced pressure at a temperature not higher than 40° C., and subjected to silica gel chromatography (eluent: n-hexane: ethyl acetate=1:1) for purification to obtain 0.92 g of the title compound (yield 71%).
