  3'-氟7-脱氮嘌呤核苷作为抗动素的合成与评价

  摘要：

  运动质体寄生虫是被忽视的热带病的病原体，医疗需求未得到满足。这些寄生虫无法从头合成嘌呤环，因此只能依靠嘌呤挽救来满足其嘌呤需求。因此，评价嘌呤核苷类似物是鉴定抗动素体药物的一种有吸引力的策略。几种抗克氏锥虫和抗布鲁氏锥虫先前已发现7-脱氮嘌呤核苷，并去除了3'-羟基，从而显着提高了活性。因此，在这项工作中，我们决定评估在7-脱氮嘌呤核苷中引入3'-氟取代基对抗动素体活性的影响。因此，我们合成了两个系列的3'-脱氧-3'- fluororibofuranosyl和3'-脱氧-3' - fluoroxylofuranosyl核苷包括7-脱氮腺嘌呤和次黄嘌呤碱，并测定这些对于抗寄生虫活性。发现了几种对克鲁斯氏锥虫和布鲁氏菌具有有效活性的类似物，表明3'-位的氟原子是发现抗寄生虫核苷的有前途的修饰。

  purine-modified 2′,3′-dideoxy-2′,3′-difluro-D-arabinonucleosides, including fluorinated analogs of fludarabine and nelarabine, have been prepared via anion glycosylation reactions of salts of 2-fluoropurine derivatives with the glycosyl bromide. A short and efficient synthetic route to the carbohydrate precursor 5-O-benzoyl-2,3-difluoro-α-d-arabinofuranosyl bromide was developed in five steps from d-xylose

• A Novel Route for the Synthesis of Deoxy Fluoro Sugars and Nucleosides

  DOI：10.1002/(sici)1522-2675(19991110)82:11<2052::aid-hlca2052>3.0.co;2-7

  The reaction of (diethylamino)sulfur trifluoride (DAST) with methyl 5-O-benzoyl-beta-D-xylofuranoside (1) followed by column chromatography afforded the riboside 2 (62%) and the ribo-epoxide 3 (18%) (Scheme 1). Under similar reaction conditions, the alpha-D-anomer 4 gave the riboside 5 and the difluoride 6 in 60 and 9% yield, respectively Treatment of the beta-D-xyloside 10 with DAST gave, after chromatographic purification, the riboside 11 as the principal product (48% 1 Scheme 2). These results suggest that the C(3)-O-SF2NEt2 derivatives were initially formed in the case of the xylosides studied. The distinctive feature of the reaction of DAST with the beta-D-arabinoside 12 consists in the formation of a 3- or 5-benzylideneoxoniumyl-substituted intermediate on one of the consecutive transformations, which finally give rise to the inversion of the configuration at C(3) affording the xylosides 17 (18%) and 18 (55% ): the lyxoside 14 was also isolated from the reaction mixture in a yield of 25% (Scheme 3). In the presence of the non-participating 5-O-trityl group, i.e.,from the reaction products of 21 with DAST. the compounds 23 and 23 were isolated in 16 and 52% yield, respectively (Scheme 4). It may be thus reasonable to conclude that, in the case of the beta-D-arabinosides 12 and 21, the principal route of the reaction is the formation of the intermediate C(2)-O-SF2NEt2 derivative. Unlike the alpha-D-arabinoside 26 was converted to the lyxo-epoxide 25 (53%) and the lyxoside 27 (14%), which implies the intermediate formation of the C(3)-O-SF2NEt2 derivative (Scheme 5).
