Cycloaddition Reaction of Dimethyl Acetylenedicarboxylate with 2,4,5-Triphenyl-3H-pyrrol-3-one 1-Oxide

The reaction of 2,4,5-triphenyl-3H-pyrrol-3-one 1-oxide with dimethyl acetylenedicarboxylate gave pyridine 9a, 4(3H)-pyridone 10a, isoxazolidine 11, and traces of pyridone 13.Pyridone 10a is not an intermediate in the formation of 9a, yet on photolysis or pyrolysis above its melting point, 10a yielded pyridine 9a.Possible reaction mechanisms that rationalize the formation of these products are discussed.
