Azide- or fluorine-containing 2′ & 3′-azolyluridines by regioselective opening of 1-(2′,3′-anhydro-β-d-lyxofuranosyl)uracils
摘要:
Azide- or fluorine-containing imidazol-1-yl, pyrazol-1-yl, and 1,2,4-triazol-1-yl 2',3'-dideoxyuridines have been synthesised from uridine in 5-6 steps, via <<2',3'-beta-epoxy>> derivatives. Regioselective oxirane-ring openings have been accomplished by appropriate choice of the reaction conditions.
