1,3-Dinitro[b, f][1,4]dibenzoxazepin-11(10H)-one enters nucleophilic substitution reactions with N-nucleophiles, azide ion preferably replacing the nitro group in position
3, whereas amines the one in position 1. Structures of the substitution products were confirmed by X-ray diffraction and 1H NMR NOE spectroscopy. The selectivity observed in the reaction with amines was supposed to be caused by the stabilization
of the intermediate σ-complex with the NH…O intramolecular hydrogen bond.
