摘要:
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.
摘要:
Pseudo-isocytidine is disclosed as well as methods and intermediates useful in its preparation. The novel compound pseudo-isocytidine, preferably the beta-anomer thereof, is an active cytostatic and anti-leukemic agent.

摘要:
A method for synthesizing monofluoromethyl- and difluoromethyluracil nucleosides from the corresponding thymine nucleosides is developed. These compounds which contain a partially fluorinated methyl group at the C-5 position (a new class of nucleosides) are potential antiviral and/or anticancer agents. The major features of the preparative route involve bromination of suitably protected thymine nucleosides followed by fluoride treatment.
