Article abstract of DOI:10.1002/hlca.19840670320

Highly substituted 4-keto-1-nitroalkanes cyclize under basic conditions to dihydro-1,2-oxazine N-oxides.These N-oxides are thermally unstable and decompose to 1,4-diketones.BF3 catalyzes a similar decomposition, but probably via a different mechanism.
