Related to synthetic study on γ-pyrone-containing natural products, conversions of β-triketides having unstable substituents to the corresponding γ-pyrones have successfully been accomplished by the new methods under conditions using (CH₃)₂S⁺C1 or Ph₃P+CX₃ (or Ph₃P⁺X, X =C1, Br) as the oxygen acceptors.
