A synthesis of mono-, di- and tri-substituted pyran-4-ones from isoxazoles is reported. The isoxazoles can be synthesized from readily available starting materials and undergo a reductive cleavage reaction with Mo(CO)6 to generate enaminoketone intermediates, which are then cyclized to pyran-4-ones under acidic conditions.
