novel approach to the synthesis of purine derivatives (bases and nucleosides) bearing 4,5-dihydrofuran-2-yl and tetrahydrofuran-2-yl substituents at the 6-position as partly and fully saturated analogues of biologically active 6-hetarylpurine nucleosides is reported. Palladium-catalyzed cross-coupling reactions of 6-iodopurines with new (4,5-dihydrofuran-2-yl)zinc chloride (1) gave 6-(4,5-dihydrofuran-2-yl)purines
合成在 6 位带有 4,5-二氢呋喃-2-基和四氢呋喃-2-基取代基的嘌呤衍生物(碱基和核苷)作为生物活性 6-杂芳基嘌呤核苷的部分和完全饱和类似物的新方法是报道。钯催化的 6-碘嘌呤与新的 (4,5-二氢呋喃-2-基) 氯化锌 (1) 的交叉偶联反应以高产率得到 6-(4,5-二氢呋喃-2-基) 嘌呤。它们的催化氢化得到6-(四氢呋喃-2-基)嘌呤。这些修饰的嘌呤碱基和核苷没有表现出任何显着的细胞抑制或抗 HCV 活性。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
