The behaviour of 4-alkoxymethylene-2-phenyl-4H-oxazol-5-one and 4-dimethylaminomethylene-2-phenyl-4H-oxazol-5-one toward nitrogen nucleophiles under microwave heating

The reactivity of 4-ethoxymethylene-2-phenyloxazol-5(4H)-one and 4-dimethylaminomethylene-2-phenyloxazol-5(4H)-one toward amines and active methylene reagents under microwave heating is reported. A new 3-aroylamino-4-pyridone synthesis is described.
