A novel method for the synthesis of 3-fluoro-4-aryl-2-pyridone via unprecedented denitration
A simple and novel method to the synthesis of 3-fluoro-4-aryl-2-pyridone from a Michael-adduct of fluoronitroacetate and α,β-unsaturated ketone is reported. With (NH4)2CO3 as the N-source and TsOH as the promoted acid, a s
