Abstract
Depending on the nature of the substituents in the starting reagents and the basicity of the medium the cyclization of N-R-2-cyanothioacetamides with ethyl [(aryl)hydrazono]chloroacetates gives 3-aryl-2-cyanomethylidene-5-ethoxycarbonyl-1,3,4-thiadiazoles, 5-arylhydrazono-2-cyanomethylidene-3-phenyl-thiazolidin-4-ones, di[(aryl)hydrazono](ethoxycarbonylmethyl) sulfides, and 5-amino-3-cyano-2-phenyl-amino-4-(N-phenylaminothiocarbonyl)thiophene.
