Reaction between o-aminothiophenol and 4-(2-furyl)-3-nitrobut-3-en-2-one affords 4-methyl-3-nitro-2-(2-furyl)-2,5-dihydro-1,5-benzo-thiazepine whose structure was characterized by X-ray diffraction analysis.

Reactions of 2-aryl(heteryl)-1-acetyl(benzoyl)-1-nitroethenes with 2,3-dimethyl-1,3-butadiene led to the formation of products of [4+2]-cycloaddition, 1-acyl-6-aryl(heteryl)-3,4-dimethyl-1-nitro-3-cyclohexenes. Their structure was proved by IR and H-1 NMR spectroscopy.
