Reactions of the Z-isomers of alkylaromatic 1,2-hydroxylamino oximes (that contain the hydroxylamino group at the primary or secondary carbon atom) with methylglyoxal gave 6-acetyl-5,6-dihydro-4H-1,2,5-oxadiazines. Analogous reactions with arylglyoxals in the presence of trifluoroacetic acid afforded 6-aroyl-5,6-dihydro-4H-1,2,5-oxadiazines. It was found that phenylglyoxal in the absence of the acid yielded N-substituted a-aroylnitrone which undergoes cyclization into the corresponding oxadiazine under the action of CF3COOH.
