Reaction Steps

To a solution of crude 1-methoxy-3,5-dioxo-5-phenylpent-1-en-2-yl acetate (3.5 mmol) in toluene (35 mL) was added pyridinium j-toluenesulfonate (130 mg, 0.5 mmol). The reaction mixture was heated at reflux under a nitrogen atmosphere for 1 h before being cooled and concentrated under reduced pressure and purified by flash chromatography (80 g Si02, 0-100% ethyl acetate/hexanes gradient elution) to provide 4-oxo-6-phenyl-4H-pyran-3-yl acetate. LC/MS (M+H)+ 231.
