Reactions of cyanothioformamide and thiohydantoin derivatives with some arylidenes of cyanothioacetamide and other elecetrophilic and nucleophilic reagents

N-(1,5-Dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazol-4-yl) cyanothioformamide was synthesized from the corresponding 4-amino-pyrazole. Various cyanothioformamides were reacted with different arylidenes of cyanothioacetamide to produce either 4-imino-5-th

A comparative study of 4-thioxo-(imidazolidines and oxazolidines) and some nucleophilic reagents

The imidazolidines (II) were reacted with amines, H2S and ?-phenylenediamines to give 4-substituted imino derivatives (VI), thiohydantoin (VII) and 1-phenyl-3 -substituted-1H-imidazo[4,5-b]-quinoxaline-2-(3H)-ones(XIII), respectively. Interaction of the oxazolidines (V) with amines, ?-phenylenediamines and ?-aminophenol caused fission of the oxazole ring to produce (XIV, XVII & XIX) respectively.
