A practical synthesis of 9-(2,3-dideoxy-2-fluoro-β-d-threo-pentofuranosyl)adenine (1, FddA) via a 6-chloro-9-(3-deoxy-β-d-erythro-pentofuranosyl)-9H-purine (6) is described. Fluorination at the C2′-β position of the purine 3′-deoxynucleoside was improved by the introduction of 6-chloro group, and proceeded in moderate yield. The total yield of FddA from readily available starting material 6 was 35%
9-(2,3-二脱氧-2-氟-β-D-的实际合成苏-pentofuranosyl)腺嘌呤(1经由6-氯-9-(3-脱氧β-D-,FDDA)赤-呋喃戊糖基)-9 ħ嘌呤(6)进行说明。嘌呤3'-脱氧核苷C2'-β位置的氟化反应通过引入6-氯基得以改善,并以中等收率进行。来自容易获得的起始原料6的FddA的总产率为35%。
