  3-Deazaguanosine, an antiviral nucleoside, was synthesized from uridine via lithiation of a C-2 protected imidazole nucleoside, which has been devised as a method for introducing various functionalities to the C-5 position. This furnished the first successful example of the conversion of a naturally occurring nucleoside to a deazapurine nucleoside.
