Abstract: A series of new hybrid molecules containing 2-furyl and partially saturated pyridine fragments was obtained based on the reaction of cyanothioacetamide with furfural and 1,3-dicarbonyl compounds. The resulting compounds were tested in vivo for analgesic activity (rats) in the orofacial trigeminal pain test. Some the tested compounds showed an antinociceptive effect, superior to that of the reference drug (metamizole sodium).

Two alternative methods for the synthesis of biologically important pyridin-2(1H)-one derivatives have been developed. The behavior of enamine 1 with aromatic amines in an aqueous solution of HCl resulted in the formation of substituted enamines 2a-f at ambient temperature. The obtained product enamines 2a-f, upon treatment with 2,2,6-trimethyl-4H-1,3-dioxin-4-one, generated pyridin-2(1H)-one derivatives 5a-f along with the unwanted side products 8a-f. However, the exclusive formation of pyridin-2(1H)-one derivatives 5a-f was achieved when starting from β-enaminones 3a-f, which were synthesized successfully from enamine 1 and aromatic amines at elevated temperatures. Compounds 2 and 3 have been used as precursors in the synthesis of pyridin-2(1H)-one derivatives. Temperature-dependent reaction diversity was observed for enamine 1 and the exclusive formation of pyridin-2(1H)-one derivatives 5 was possible.
