The synthesis of several heterocyclic analogues of the biologically important nucleoside antibiotic toyocamycin and the tricyclic nucleoside triciribine (TCN) were prepared along with their 2'-deoxy counterparts. Coupling of 2-nitropyrrole-3,4-dicarboxamide (15) under a variety of conditions with alpha-chloro-2-deoxy-3,4-di-O-toluoyl-D-ribofuranose (16a) gave mixtures of the alpha and beta anomers. A coupling of 15 with 1-chloro-2,3,5-tri-O-benzoyl-D-ribofuranose (18) gave exclusively the beta anomer. Individually, the two pyrrole nucleosides were treated with Pd/C, H2 to reduce the nitro groups and cyclized with nitrous acid, and the corresponding 4-position was functionalized as a triazoyl derivative. Nucleophillic displacement was carried out with ammonia to give a mixture of 4-amino-1-(2,3,5-tri-O-benzoyl-beta-D-ribofuranosyl)pyrrolo[2,3-d][1,2,3]triazine-5-carbonitrile (26) and 2-amino-1-(2,3,5-tri-O-benzoyl-beta-D-ribofuranosyl)pyrrole-3,4-dicarbonitrile (27), the latter being formed via a retro-Diels-Alder reaction.

A novel synthesis of a new class of 2-(beta-D-ribofuranosylthio)pyridine glycosides utilizing the reactions of substituted pyridine-2(1H)-thiones and 1-O-acetyl-2,3,5-tri-O-benzoyl-D-ribofuranose as starting components is described.

A series of 2-halogen and 7-alkyl substituted analogues of 9-deazaadenosine and 2'-deoxy-9-deazaadenosine was synthesized by new efficient methodology involving transformation of corresponding 9-deazaguanosine and 2'-deoxyguanosine, which in turn were synthesized by direct C-glycosylation of 1-benzyl-9-deazaguanine with 1-O-acetyl-2,3,5-tri-O-benzoyl-D-ribofuranose and methyl 2-deoxy-3,5-di-O-(p-toluoyl)-D-ribofuranoside, respectively. Deoxychlorination of C6 and diazotization/chloroor fluoro-dediazoniation of the sugar-protected 9-deazaguanosine, followed by selective ammonolysis at C6 and deprotection of the sugar moiety, gave 2-chloro- and 2-fluoro-9-deazaadenosine (6 and 9). Substitution of the 7-position of the dihalogen-intermediate with alkyl groups, followed by ammonolysis and deprotection, provided 2-chloro-7-alkyl-9-deazaadenosines (13a-e) and 2-fluoro-7-benzyl-9-deazaadenosine (13f). Catalytic hydrogenation of 13a-e gave 7-alkyl-9-deazaadenosines 14a-e.

2,6,8-Trichloro-7-methylpurine (3) was converted to 2-chloro-8,9-dihydro-7-methyl-8-thioxopurin-6(1H)-one (5) by utilizing the difference in reactivity of the 2-, 6-, and 8-positions in the trichloropurine ring system to nucleophilic displacement. Compound 5 was subsequently glycosylated with 1-O-acetyl-2,3,5-tri-O-benzoyl-D-ribofuranose according to the Vorbrüggen procedure to yield 2-chloro-8,9-dihydro-7-methyl-9-(2,3,5-tri-O-benzoyl-beta-D-ribofuranosy l)-8- thioxopurin-6(1H)-one (6). Removal of the benzoyl protecting groups, followed by amination of 7 with liquid ammonia at 150 degrees C, gave 7,8-dihydro-7-methyl-8-thioxoguanosine (2). The structure of compound 2 was confirmed by X-ray crystallographic analysis. Compounds 1 (7,8-dihydro-7-methyl-8-oxoguanosine) and 2 were evaluated for activity in various animal virus infection models. Against banzi, Semliki Forest, and San Angelo viruses in mice, 2 was highly active when administered before virus inoculation.
