    公开(公告)日:1998-08-11
    Herein is disclosed a novel and industrially advantageous process for synthesizing acyclic nucleosides such as acyclovir and ganciclovir from ribonucleosides, which process comprises adding an acid catalyst and an acid anhydride to a solution of a ribonucleoside such as guanosine and an ester derivative of an acyclic sugar, and heating the mixture, whereby a transglycosilation reaction takes place between the ribose moiety of the ribonucleoside and the ester derivative of the acyclic sugar. Herein is also disclosed an industrially favorable method for the separation of 9-substituted purine nucleosides which are important intermediates for the synthesis of acyclic nucleosides such as acyclovir, ganciclovir, and the like from ribonucleosides, which method comprises crystallizing only the 9-isomer from a solution or suspension containing both a 9-substituted purine nucleoside and a 7-substituted purine nucleoside by cooling the solution or/and by adding a crystallizing solvent thereto.

  • Regioselectivity and mechanism of transpurination reactions in the guanine nucleosides series
    作者:Jerzy Boryski
    DOI:10.1039/a602021f
    日期:——
    The transpurination reaction of the fully acetylated derivatives of guanosine and its 7-β-D-ribofuranosyl regioisomer with 2-acetoxyethyl acetoxymethyl ether has been studied using high performance liquid chromatography (HPLC). The regioselectivity of glycosyl exchange observed in the early stages of the reaction suggests that the unsubstituted nitrogen atoms of the imidazole portion (N7 and N9) are, exclusively, sites of direct glycosylation in the case of guanine derivatives. The results lead to the conclusion that the mechanism of the glycosylation reaction of guanine is different to that of adenine.
    我们使用高效液相色谱法(HPLC)研究了鸟苷的完全乙酰化衍生物及其 7-β-D-ribofuranosyl regioisomer 与 2-acetoxyethyl acetoxymethyl ether 的转urination 反应。在反应初期观察到的糖基交换的区域选择性表明,在鸟嘌呤衍生物中,咪唑部分的未取代氮原子(N7 和 N9)是直接糖基化的唯一位点。研究结果得出结论,鸟嘌呤的糖基化反应机制与腺嘌呤不同。
  • Purine Nucleoside Analogues. 11. An Alternative Synthesis of N- and O-Alkyl Derivatives of 9- and 7-[(2-Acetoxyethoxy)methyl]-N2-acetylguanine
    作者:Marina Madre、Natella Panchenko、Alexander Golbraikh、Regina Zhuk、Upendra K. Pandit、Jan Geenevasen、Gerrit-Jan Koomen

    Alkylations of 9- and 7-[(2-acetoxyethoxy)methyl]-N2-acetylguanine with alkyl halogenides in the presence of base have been investigated affording a new route to the preparation of 1,N2-dimethyl- as well as O6-benzyl-9(7)-alkoxyalkylguanines. 1H NMR spectra revealed that the 1,N2-dimethyl derivatives exist as mixtures of two conformers at room temperature due to the restricted rotation about the C2-N2 bond. These findings agreed with conformational calculations.

    在碱的存在下,使用烷基卤化物对9-和7-[(2-乙酰氧乙氧基)甲基]-N2-乙酰基鸟嘌呤进行烷基化反应的研究,提供了制备1,N2-二甲基以及O6-苄基-9(7)-烷氧基烷基鸟嘌呤的新途径。1H NMR光谱显示,由于C2-N2键的受限旋转,1,N2-二甲基衍生物在室温下存在两种构象的混合物。这些发现与构象计算一致。
