  名称：

  Synthesis of 3-(2-deoxy-β-d-ribofuranosyl)pyridin-2-one and 2-amino-6-(N,N-dimethylamino)-9-(2-deoxy-β-d-ribofuranosyl)purine derivatives for an unnatural base pair

  摘要：

  An unnatural base pair, 2-amino-6-(N,N-dimethylamino)purine (denoted x) and pyridin-2-one (denoted y), was designed to prove the structural requirements for base pair formation involving shape complementarity. It was expected that y might satisfy the structural requirements for pairing with x, in which the bulky 6-dimethylamino group may eliminate base pairing with the natural bases. As chemical or biological substrates for DNA synthesis, the phosphoramidite of x and the 2'-deoxy-C3-ribonucleoside triphosphate of y (dyTP) were synthesized, and the incorporation experiment was demonstrated by using the Klenow fragment of Escherichia call DNA polymerase I.

  摘要：

  腺苷1-N-氧化物经酶促脱氨基作用生成1-羟基次黄嘌呤（2a），随后乙酰化并氯化得到2,6-二氯-9-(2,3,5-三-O-乙酰-(β-D-核糖呋喃糖基)嘌呤（3）。干燥的1,2-二甲氧基乙烷中的氨转化3为2-氯腺苷三乙酸酯（4a）。在乙腈中，用三甲胺在高温下处理4a导致形成2-N,N-二甲基氨基腺苷三乙酸酯（4b）。瓜嘌呤（5）通过改进的方法顺利地被乙酰化。得到的三乙酸酯（6）在约85%的产率下氯化，生成2-氨基-6-氯-9-(2,3,5-三-O-乙酰-β-D-核糖呋喃糖基)嘌呤（7）。用三甲胺在室温下处理7 28小时，得到6-N,N-二甲基氨基化合物（8d）。然而，钾氟化物或氯化钠与DMF或乙腈中的催化量三甲胺反应，产率大于90%地生成2-氨基-6-氟（8a）或2-氨基-6-叠氮（8b）产物。
