Article abstract of DOI:10.1016/0040-4020(82)80237-8

1,2-Oxazine N-oxides derived from aminocyclohexenes open into the corresponding nitroalkylated trisubstituted enamines, whereas those derived from aminocyclopentenes give stable tetrasubstituted enamines.Both open-chain systems are easily hydrolyzed to the corresponding χ-nitrocycloalkanones.
