A CuI/KF mediated perfluoroalkylation reaction of various 9-substituted 6-iodopurines 1 with trimethyl(trifluoromethyl)silane or heptafluoropropyl(trimethyl)silane was used for the synthesis of the corresponding 6-(trifluoromethyl)- and 6-(heptafluoropropyl)purine derivatives (purine bases, nucleosides and acyclic nucleotide analogues) in moderate to good yields.
使用CuI/KF介导的全氟烷基化反应,将各种9-取代的6-碘嘌呤1与三甲基(三氟甲基)硅烷或七氟丙基(三甲基)硅烷反应,可合成相应的6-(三氟甲基)-和6-(七氟丙基)嘌呤衍生物(嘌呤碱基、核苷和非环核苷酸类似物),收率中等至良好。
