The synthesis of (E)-3′-phosphonoalkenyl and 3′-phosphonoalkyl modified nucleoside analogues with a β-d-erythrofuranose moiety is reported. The highly stereoselective olefin cross-metathesis reaction was applied to introduce the phosphonoalkenyl group at the 3′-position of the sugar moiety with absolute (E)-selectivity. The 3′,6′-cyclomonophosphonic acids of 3′-phosphonoethyl-β-d-erythrofuranosyl nucleosides
报道了具有(E)-3'-膦烯基和3'-膦烷基修饰的具有β- d-呋喃呋喃糖部分的核苷类似物的合成。进行高度立体选择性的烯烃交叉复分解反应,以绝对的(E)选择性在糖部分的3'-位置引入膦酰基烯基。通过脱水分子内环化反应合成了3'-膦酰基乙基-β- d-赤藓呋喃糖基核苷的3',6'-环一膦酸。合成的化合物均未显示出针对HIV,HCV和RSV的显着体外活性。
