In its absorption spectrum, the typical band for nitro groups at 270 nm is missing, which suggests the formation of hydrogen bonds with the participation of the nitro group. Under the action of alkali a retro-aldole condensation takes place with the elimination of formaldehyde. The reaction of the nitrosubstituted glycol with formaldehyde and cyclohexylamine yields substituted 1,3-oxazines in a three-component reaction.
