Controlled ozonolysis of (S)-(–)-limonene in the presence of Py gave 4-methyl-3-(3-oxobutyl)pent-4-enal or 4-methyl-3-(3-oxobutyl)pent-4-enoic acid depending on the solvent (CH2Cl2 or MeOH). Exhaustive ozonolysis produced 3-acetyl-6-oxoheptanoic acid. Ozonolysis of abietic acid in CH2Cl2 in the presence of Py formed stable epoxytrioxolaneabietic acid; in MeOH–Py, the epoxyketoaldehyde corresponding to cleavage of the C13–C14 bond.
