The first example of aza-annulation of β-aminovinyl trifluoromethyl ketones with acryloyl chloride has been studied. 5-Trifluoroacetyl-containing 3,4-dihydro-2(1H)-pyridinones 3a–j were obtained from β-substituted enaminones 2a–j, whereas β-unsubstituted enaminone 4 gave a mixture of cyclic and acyclic products.

The NH- and α-CH-insertion reactions of tosyl isocyanate with N-monosubstituted and N,N-disubstituted trifluoromethyl-containing enaminones have been studied. The regioselectivity of N-tosylcarbomoylation of N-monosubstituted β-aminovinyl trifluoromethyl ketones depends on the structure of enaminones, the reaction temperature, the nature of solvent and catalyst.
