Abstract: The nitrogen-bridged compound 2,2'-anhydro-1-beta-D-arabinofuranosyl-2,4-diamino-5-fluoropyrimidinium chloride (2), an analogue of the antitumor agent anhydro-ara-FC (1), has been synthesized. 5-Fluorocytidine was converted into 1-beta-D-ribofuranosyl-2,4-diamino-5-fluoropyrimidinium chloride (4), but cyclization of 4 was not achieved due to a competing side reaction. The nitrogen bridge was therefore introduced by cyclization of 5-fluoroisocytidine (10) to give the 2,2'-imino-bridged compound 16. The latter was converted into 2 by the standard procedure of thiation, S-methylation, and treatment with ammonia. Compound 2, as well as a number of the synthetic intermediates, was tested for activity against S180 sarcoma in mice. None of the new compounds exhibited any antitumor activity.
