Article abstract of DOI:10.1055/s-1994-25645

Aromatic and aliphatic N,O-divinylhydroxylamine systems generated in situ from hydroxylamine derivatives smoothly undergo [3,3] rearrangement. The base-catalyzed formation and rearrangement of enolates or dienolates of N-aryl-O-acylhydroxylamines, N,O-dia
