Abstract: The title 3-amino-2-thiohydantoins 3 has been prepared in very good yields by the reaction of alkyl isothiocynatocarboxylates 1 with hydrazine hydrate.The synthesis of starting isothiocyanates as well as spectral data of 3-aminothiohydantoins and alkyl isothiocyanatocarboxylates has been presented.

Keywords: thiohydantoin; isothiocyanate; thiosemicarbazide; agrochemicals
