  ABSTRACT: A reaction of tetrahydropyridines, obtained by the Diels-Alder reaction from α,β-unsat-urated N,N-dimethylhydrazones and methyl acrylate, with acetylenes activated with the trifluoroacetyl group has been studied and found to lead to polysubstituted trifluoroacylated tetrahydroazocines. No cyclobutene intermediates have been detected. Key wordstrifluoroacetylacetylenes-tetrahydropyridines-[2+2] cycloaddition-ring expansion-tetrahydroazocines

  ABSTRACT: Halogenated trifluoroacetylacetylenes have been synthesized for the first time. It was shown that they undergo formally forbidden by the orbital-symmetry rules [2+2] cycloaddition reactions with nonactivated alkenes in the absence of light and catalyst. A possible mechanism for this transformation is suggested. Key wordstrifluoroacetylacetylenes-[2+2] cycloaddition reactions-ene reactions

  ABSTRACT: Unusual cascade cycloaddition reactions with dimethylhydrazones of -trimethylsilyloxyalkylacroleins acting as azadienes were found. Depending on the nature of the dienophile, the reactions give either fused heterocyclic compounds (when two consecutive Diels—Alder reactions take place) or azabicyclic compounds, resulting from the [2+4]- and [2+3]-cycloaddition cascade.
