A mixture of 3 mmol of diethyl cinnamate, 3 ml of 2-propanol, 0.6 mmol of N-hydroxyphthalimide, 0.015 mmol of cobalt(II) acetate, 0.03 mmol of acetylacetonatocobalt(III), and 1 ml of acetonitrile was stirred at 70° C. in an oxygen atmosphere (1 atm) for 12 hours. A gas chromatographic analysis of products in a reaction mixture revealed that α-hydroxy-β-phenyl-γ,γ-dimethyl-γ-butyrolactone and ethyl 2,4-dihydroxy-4-methyl-3-phenylpentanoate were formed in yields of 18% and 24%, respectively. The conversion rate from diethyl cinnamate was 61%.
