A methodology for the asymmetric peroxidation of γ,δ-unsaturated β-ketoesters is presented. Using a cinchona-derived organocatalyst, the target δ-peroxy-β-keto esters were obtained in high enantiomeric ratios of up to 95:5. Additionally, these δ-peroxy esters can be readily reduced to chiral δ-hydroxy-β-keto esters without impacting the β-ketoester functionality. Importantly, this chemistry opens
