The Formation of Dihydro‐1,2‐oxazine N ‐Oxides through an Intramolecular Addition of a Nitronate Anion to a Carbonyl Group 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, BF 3 catalyzes a similar decomposition, but probably via a different mechanism.
