3â²-Substituted pyrimidine nucleoside derivatives are obtained in moderate to high yields by the reactionof 1-(2â²,3â²-anhydro-5â²-deoxy-4â²,5â²-didehydro-α-L-erythro-pentofuranosyl)uracil with nucleophiles without the formation of the corresponding 2â²-adduct.
通过 1-(2â²,3â²-anhydro-5â²-deoxy-4â²,5â²-didehydro-δ-±-L-erythro-pentofuranosyl)uracil 与亲核物反应,可获得中等至高产率的 3â²-取代
嘧啶核苷衍
生物,且不会形成相应的 2â²-加合物。
