The synthesis of hitherto unknown C5-substituted O6,5′-cyclouridines is described. The 2′,3′-isopropylidene-uridine was treated with N-halogenosuccinimides forming appropriate bridged 5-halogeno derivatives. Using lithiation method, bromine substituent at C5 position was exchanged into various alkyl and alkenylderivatives.
