Abstract: 1,3-Thiazin-4-one derivatives were synthesized by boron trifluoride-catalyzed intramolecular cyclization of N-substituted N'-(hexa-2,4-dienoyl)thioureas and by the reaction of hexa-2,4-dienoyl isothiocyanate with sodium hydrogen sulfide. The structure of the prepared compounds was confirmed by their IR, ¹H  and ¹³C  NMR spectra.
