  A Facile Route to Pyrimidine-Based Nucleoside Olefins: Application to the Synthesis of d4T (Stavudine)

  摘要：

  An efficient synthetic route to nucleoside olefins in the uridine, cytidine, and thymidine series is described which utilizes the Garegg-Samuelsson iodine/triphenylphosphine/imidazole-promoted deoxygenation of the 2',3'-hydroxyl groups as the key step. Cyclopentylidene ketal protection was employed for all the nucleoside 2',3'-hydroxyls to facilitate blocking of the 5'-hydroxyl and the pyrimidine nitrogens with the benzyl or 4-methoxybenzyl (PMB) groups. Deblocking of the cyclopentylidene group followed by olefination of the resulting diols provided protected nucleoside olefins 18-20. Starting with 5-methyluridine 4 and utilizing the 4-methoxybenzyl group for 5',N-3 protection, the overall scheme provided the anti-HIV compound d4T (1) after deprotection of the PMB groups. The dibenzylhypoxanthine nucleoside diol 17 derived from inosine gave either unreacted starting material or decomposition products under several sets of conditions.

  摘要：

  基于我们先前的发现，即5'-O-三苯甲基肌氨酸（KIN59）可以作为血管生成酶胸苷磷酸化酶（TPase）的变构抑制剂，我们已经进行了合成和酶促评估，研究了一系列在位置修饰的核苷类似物嘌呤环的1、2或6，以及先导化合物KIN59的核糖部分的5'-位置。SAR研究表明，可以在KIN59上进行相当大的结构变异，而不会影响TPase抑制作用。因此，与KIN59相比，在5'-O-三苯甲基肌氨酸的N（1）位上引入环丙基甲基或环己基甲基基团提高了对TPase的抑制活性10倍。此外，核糖5'-位的三苯甲基似乎对TPase抑制至关重要。

  A synthetic method for 2 ′,3 ′-dideoxyinosine (ddI) from inosine was established via radical deoxygenation of N1,5 ′-O-diprotected-2 ′,3 ′-bis-S-methyl dithiocarbonate of inosine derivatives. The radical deoxygenation proceeded smoothly to give the desired dideoxy compounds in good yields using 1-ethylpiperidinium hypophosphite and triethylborane.

  On the basis of our previous findings that 5'-O-tritylinosine (KIN59) behaves as an allosteric inhibitor of the angiogenic enzyme thymidine phosphorylase (TPase), we have undertaken the synthesis and enzymatic evaluation of a novel series of nucleoside analogues modified at positions 1, 2, or 6 of the purine ring and at the 5'-position of the ribose moiety of the lead compound KIN59.
