  A simple and efficient synthesis of 9-substituted guanines. Cyclodesulfurization of 1-substituted 5-[(thiocarbamoyl)amino]imidazole-4-carboxamides under aqueous basic conditions

  摘要：

  5-Aminoimidazole-4-carboxamide (AICA) (1a) is 1-alkylated by an improved method. The resulting 5-amino-1-alkylimidazole-4-carboxamides (1b-i) are converted to the corresponding 1-alkyl-5-[(thiocarbamoyl)-amino]imidazole-4-carboxamides (3). These compounds are ring closed under alkaline conditions to 9-substituted guanines (5) in very high yields by treatment with heavy-metal salts in aqueous sodium hydroxide, or, in somewhat lower yields, by S-oxidation with hydrogen peroxide or sodium perborate in aqueous sodium hydroxide.

  Modification at the 5' position yielded the deoxy, iodo, and phosphate derivatives 15, 13, and 16, as well as the cyclic 3',5'-phosphate 17. The synthesis of the C-nucleoside analogue 19 was achieved from the beta-D-ribofuranosylcarboximidic ester 20. The acyclic analogue 29 and the beta-D-arabinofuranosyl derivative 35 were both synthesized by reaction of methyl isocyanate with the appropriately protected

  Hydroxyl-protected derivatives of 1- and 3-(2-hydroxyethoxymethyl)imidazoles (4,5,7-10) have been prepared from 5-amino-4-carbamoylimidazoles (2). The protected derivatives were converted to acyclic analogues of imidazole nucleosides (6) or subjected to various cyclisation reactions leading to 9-(2-hydroxy-ethoxymethyl)-substituted 2-methyl-, 2-phenyl- and 2-azahypoxanthines (18,13 and 20, respectively)

• Modifications on the heterocyclic base of acyclovir: syntheses and antiviral properties

  A group of compounds was prepared in which variations of the ring portion of the acyclovir (ACV) structure were made. These modifications included monocyclic (isocytosine, triazole, imidazole), bicyclic (8-azapurine, pyrrolo[2,3-d]pyrimidine, pyrazolo[3,4-d]pyrimidine) and tricyclic (linear benzoguanine) congeners. The derivatives were evaluated against herpes simplex virus type 1 (HSV-1) by the plaque-inhibition and plaque-reduction methods with only the 8-azapurine analogue 28 showing some activity. In a test measuring the ability of these compounds to inhibit the HSV-1 thymidine kinase, 28 and the tricyclic derivative 38 exhibited competition with ACV for binding to the enzyme. The inability of the group to exert significant antiherpetic action is attributed to their lack of phosphorylation to the requisite triphosphate stage.
