Thermal rearrangement of 2-allyloxypyridine N-oxides (4a-c) yields N-allyloxy-2-pyridones (5a-c) and 3-allyl-N-hydroxy-2-pyridones (6a-c).These transformations are shown to be regiospecific and on this basis it is proposed that the reactions involve concerted and sigmatropic rearrangements.Supporting evidence based on solvent effects, temperature effects, and substituent effects is given.
