Abstract

A novel method for the introduction of fluorine in the purine 2-position is described and employed in the synthesis of a potential antimycobacterial compound. Also 2-fluoroadenosine has been synthesized for the first time from adenosine with perbenzo­ylated 2-nitroadenosine as a key intermediate. Mild reaction conditions are employed and few synthetic steps are required. The novel synthesis of fluoroadenosine can be regarded as a formal synthesis of the antileukemic drug fludarabine phosphate.
