sulfonosine (3), was synthesized by four different routes. Acid catalyzed fusion of 6-chloropurine-2-sulfonyl fluoride (5) with 1,2,3,5-tetra-O-acetyl-β-D-ribofuranose (8) gave a good yield of 6-chloro-9-(2,3,5-tri-O-acetyl-β-D-ribofuranosyl)purine-2-sulfonyl fluoride (9). Ammonolysis of 9 furnished 4. Lewis acid catalyzed glycosylation of the trimethylsilyl derivative of either 6-chloropurine-2-sulfonamide
通过四种不同的途径合成了2-氨基-9-β-D-呋喃呋喃糖基嘌呤-2-磺酰胺(2-磺酰胺基腺苷,4),是磺胺(3)的同类物。酸催化的6-氯嘌呤-2-磺酰氟(5)与1,2,3,5-四-O-乙酰基-β-D-呋喃呋喃糖(8)的融合产生了6-氯-9-(( 2,3,5-三-O-乙酰基-β-D-呋喃呋喃糖基)嘌呤-2-磺酰氟(9)。氨解9家具4。路易斯酸催化或者6-氯-2-磺酰胺(的三甲基甲硅烷衍生物的糖基化6)或6-氨基嘌呤-2-磺酰胺(7)与8给出相应的N 9糖基化产物,分别为10和11,经氨解反应得到4。2- thioadenosine(的胺化12)与氯胺溶液,得到亚磺酰胺衍生物13,其与随后的氧化米氯过氧酸配一个备用路由至4。通过单晶X射线衍射研究确定了4的结构。2-磺酰胺基腺苷(4)对小鼠的L1210白血病没有明显的抑制活性。
