Abstract: The reactions of 2-cyano-3-phenylpropenoyl isothiocyanate with aniline and secondary amines, respectively, have been studied. It has been found that stable thiourea, which in alkali medium cyclizes to the mixture of cis- and trans - 2 - thiouracils, was formed only from aniline. Secondary amines provided the mixture of the corresponding isomeric 1,3-thiazines directly. The data of elemental analysis as well as of 1H NMR and IR spectra proved the structures of the synthesized compounds.
