Abstract

There is provided a novel process for pyrimidine to pyrimidine transformations by the displacement of the 1,2,3-portion of a pyrimidine by a 1,3-ambident nucleophile. The novel process requires that the 1 and 3 nitrogens of the pyrimidine moiety be substituted. The novel process makes available, inter alia, novel uracils, simple methods of radioisotopically labeling pyrimidine nuclei, a simple and inexpensive method of preparing the important antiviral and antileukemic material pseudoisocytidine and its new active analog 2'-deoxypseudoisocytidine.
