The interactions of alkyl 3-bromo-3-nitroacrylates with 1,2-diaminoethane, 1,2-diaminopropane, 1,2-diaminocyclohexane, and 2aminoethanol were shown to provide a convenient route for the synthesis of six-membered heterocycles – (3Z)-3-(nitromethylidene)piperazin-2-ones and (3Z)-3-(nitromethylidene)morpholin-2-one. The structures of the synthesized heterocycles were characterized by a range of spectral methods and by X-ray structural analysis.
