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 enamino ketone intermediates, which are then cyclized to pyran-4-ones under acidic conditions.
据报道由异恶唑合成单,二和三取代的吡喃-4-酮。异恶唑可以由容易获得的起始原料合成,并与Mo(CO)6进行还原裂解反应生成烯氨基酮中间体,然后在酸性条件下环化成吡喃-4-酮。
