  摘要：

  A general total synthetic method for the stereocontrolled synthesis of 2',3'-dideoxy- as well as 2',3'-didehydro-2',3'-dideoxynucleosides is presented. Introduction of an alpha-phenylselenenyl group at the 2-position of 2,3-dideoxyribosyl acetate directs the glycosyl bond formation to give greater-than-or-equal-to 95% beta-isomer. This 2'-phenylselenenyl nucleoside may be converted to either the 2',3'-dideoxynucleoside by treatment with n-Bu3SnH and Et3B at room temperature or to the unsaturated derivative by treatment with H2O2/cat. pyridine. The application of this method to the syntheses of pyrimidines (ddU, ddT, ddC), 6-substituted purines (ddA, ddI, 6-chloro-ddP, N6-Me-ddA), and 2,6-disubstituted purines (2-F-ddA, 6-chloro-2-amino-ddP) as well as selected 2',3'-didehydro-2',3'-dideoxy derivatives is reported.

  approved, as well as potentially antivirally active, nucleoside analogues was synthesized. The enzyme‐triggered delivery of NTPs was demonstrated by pig liver esterase, in human T‐lymphocyte cell extracts and by a polymerase chain reaction using a prodrug of thymidine triphosphate. The TriPPPro‐compounds of some HIV‐inactive nucleoside analogues showed marked anti‐HIV activity. For cellular uptake

  核苷类似物代谢转化为三磷酸酯的过程常常进行得不充分。速率限制可以在单磷酸化步骤中进行，也可以在二磷酸化和三磷酸化步骤中进行。我们开发了核苷三磷酸（NTP）递送系统（Tri PPP方法）。通过这种方法，NTP被γ-磷酸盐处的两个生物可逆单元掩盖。使用涉及H-膦酸酯化学的方法，合成了一系列带有批准的以及可能具有抗病毒活性的核苷类似物的衍生物。猪肝酯酶，人T淋巴细胞提取物中的酶触发的NTPs传递以及使用三磷酸胸苷的前药的聚合酶链式反应证明了这一点。三重PPP一些对HIV无活性的核苷类似物的ro-化合物显示出显着的抗HIV活性。为了进行细胞摄取研究，制备了荧光Tri PPP ro-化合物，该化合物将三磷酸化的代谢物递送至完整的CEM细胞。

  Two efficient syntheses of the anti-AIDS drug 2',3'-dideoxycytidine (3) from N4-acetylcytidine (4) are described. In one, silylation of the C-5' hydroxyl group of 4 with tert-butyldimethylsilyl chloride followed by treatment with 1',1'-(thiocarbonyl)diimidazole gave the cyclic thionocarbonate 7, which on reaction with 1,3-dimethyl-2-phenyl-1,3-diazaphospholidine gave the crystalline alkene 8. Hydrogenation of 8, followed by desilylation with tetrabutylammonium fluoride and hydrolysis, gave 3 in 27% overall yield from 4. In the other synthesis, 4 was converted into a regioisomeric mixture of bromo acetates 11 with 2-acetoxy-2-methylpropanoyl bromide. Reductive elimination of 11 with zinc-copper couple in acetic acid or electrochemically gave the crystalline alkene 15, whose stereostructure was established by a single-crystal X-ray analysis. Hydrogenation of 15, followed by hydrolysis, gave ddC (3). In a through process, which is suitable for large-scale work, this second synthesis gave 3 in over 40% overall yield from 4. The use of (S)-(-)-2-acetoxypropanoyl bromide, of 2-acetoxybenzoyl bromide, and of hydrogen bromide/acetic acid in the bromoacetylation of 4 is also described.
