with trifluoroacetyl acetylenes furnished the [4+2]-adducts solely. The last ones readily rearranged to the corresponding 3H-furo[4,3,2-fg][3]benzazocine derivatives. So, the use of N-acyl-N-northebaines as the starting materials in the reactions with acetylenic dienophiles provides the general methodology to avoid a formation of the undesirable “nucleophilic” adducts typical for the reactions of the
Addition reactions of 1,1,1-trifluoro-4-trimethylstannylbut-3-yn-2-one and 1,1,1-trifluorobut-3-yn-2-one to some tetrahydropyridines. Synthesis of trifluoroacylated polysubstituted tetrahydroazocines

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.
