Abstract:

Pyrimidine I-oxides with cyanamide afforded 2-ureidopyrinlidines as the result of the nucleophilic substitution of hydrogen, whereas the formation of similar 2-trichloroacetyl-aminopyrimidines occurs as dipolar 1,3-cycloaddition of the same oxides to trichloroacetonitrile under much more drastic conditions and in lower yields.
