Article abstract of DOI:10.1016/S0040-4039(97)10585-8

The rearrangement of N-sulfonyl pyridones to the corresponding O-sulfonyl pyridinols during cycloaddition can be greatly retarded by introduction of steric congestion on either the pyridone ring or the sulfonyl group. Hence, significantly improved yields
