The syntheses of 1,3,7-trideaza-2′,3′-dideoxyadenosine (1) and its 2′,3′-didehydroderivative (2b) as potential anti-HIV compounds are described. Nucleobase anion glycosylation of 4-nitroindole (4) with 1-chloro-2-deoxy-3,5-bis-O-(4-methylbenzoyl)-α-D-erythro- pentofuranose (5) yields 1-[2-deoxy-3,5-bis-O-(4-methylbenzoyl)- β-D-erythro-pentofuranosyl]-4-nitro-1H-indole (6a) stereoselectively in 85% yield. Upon detoluoylation the 3′-hydroxyl group was removed by two different routes using a mesylation/elimination process.
描述了作为潜在抗 HIV 化合物的 1,3,7-trideaza-2',3'-二脱氧腺苷 (1) 及其 2',3'-二脱氢衍生物 (2b) 的合成。 4-硝基吲哚 (4) 与 1-氯-2-脱氧-3,5-双-O-(4-甲基苯甲酰基)-α-D-赤式-呋喃戊糖 (5) 的核碱基阴离子糖基化产生 1-[2-脱氧-3,5-双-O-(4-甲基苯甲酰基)-β-D-赤式-呋喃戊糖基]-4-硝基-1H-吲哚(6a) 立体选择性地产率85%。去甲苯酰化后,使用甲磺酰化/消除过程通过两种不同的途径去除 3'-羟基。
