β-keto esters by treatment with ozone followed by the addition of tin(H) chloride and ethyldiazoacetate. Monosubstituted olefins are first treated with ozone in the presence of methanol to generate methoxy hydroperoxides. The hydroperoxides are subsequently reduced with tin(II) chloride in the presence of ethyldiazoacetate to produce β-keto esters.
