The reaction of 5-cyanouracils with thioureas and guanidines causes novel pyrimidine-to-pyrimidine ring transformations.Thus, 1,3-disubstituted 5-cyanouracils (1) react with thiourea and guanidines to give the corresponding 5-carbamoyl-2-thiocytosines (2)

The reaction of 1,3-disubstituted 5-cyanouracils (1) with thioureas (2) and sodium hydroxide causes novel pyrimidine-to-pyrimidine ring transformation to give 2-thiocytosines (3) and 6-amino-5-formyluracils (4), respectively.
