Reaction of N1-substituted uracils with bromine in water at pH=7 leads to 5-bromo-6-hydroxy-5,6-hydrouracils.For different N1-substituents these products were isolated and the relatively stable derivatives were characterized by 1H NMR and mass spectroscopy.On electrophilic iodination with iodide and chloramine-T in water no indications were obtained for the formation of such dihydrouracils except for uridine and deoxyuridine.However, on reaction of N1-substituted uracils with N-iodosuccinimide in CHCl3 containing ethanol, or in ethanol, 5-iodo-6-ethoxy-5,6-dihydrouracils could be isolated as reaction products.
