Abstract
Glycosylation of nonfunctionalized 6-chloro-7-deazapurine with commercially available 1- O-acetyl-2,3,5-tri- O-benzoyl-β-d-ribofuranose (45%) followed by amination and deprotection gave tubercidin in only two steps. Similar conditions applied for the synthesis of 7-deazaguanosine employing pivaloylated 2-amino-6-chloro-7-deazapurine gave 18% glycosylation yield. The less bulky isobutyryl or acetyl protected amino group directed the glycosylation toward the exocyclic amino substituent. 7-Halogenated intermediates were glycosylated followed by dehalogenation to overcome the low glycosylation yield in the synthesis of 7-deazaguanosine.

Abstract
Treatment of toyocamycin or sangivamycin with 1,3-dibromo-5,5-dimethylhydantoin in MeOH (r.t./30 min) gave 8-bromotoyocamycin and 8-bromosangivamycin in good yields. Nucleophilic aromatic substitution of 8-bromotoyocamycin with sodium azide provided novel 8-azidotoyocamycin. Strain promoted click reactions of the latter with cyclooctynes resulted in the formation of the 1,2,3-triazole products. Iodine-mediated direct C8-H bond functionalization of tubercidin with benzotriazoles in the presence of tert-butyl hydroperoxide gave the corresponding 8-benzotriazolyltubercidin derivatives. The 8-(1,2,3-triazol-1-yl)-7-deazapurine derivatives showed moderate quantum yields and a large Stokes shifts of ~ 100 nm.

Abstract
Dinucleoside phosphorochloridite were synthesized from phosphorus trichloride and three nucleoside analogues, 3'-fluoro-2',3'-dideoxythymidine (FLT), 2',3'-dideoxy-5-fluoro-3'-thiacytidine (FTC), and 2',3'-dideoxy-3'-thiacytidine (3TC), in a multistep synthesis. Polymer-bound N-Boc p-acetoxybenzyl 5'-O-2'-deoxythymidine was reacted with dinucleoside phosphorochloridite in the presence of 2,6-lutidine, followed by the reaction with dodecyl alcohol and 5-(ethylthio)-1H-tetrazole, oxidation with tert-butyl hydroperoxide, and acidic cleavage, respectively, to afford the β-triphosphotriester derivatives containing three different nucleosides.

Abstract
Despite the success of potent reverse transcriptase (RT) inhibitors against human immunodeficiency virus type 1 (HIV-1) in combination regimens, the development of drug resistant RTs constitutes a major hurdle for the long-term efficacy of current antiretroviral therapy. Nucleoside β-triphosphate analogs of adenosine and nucleoside reverse transcriptase inhibitors (NRTIs) (3'-azido-2',3'-dideoxythymidine (AZT), 3'-fluoro-2',3'-dideoxythymidine (FLT), and 2',3'-didehydro-2',3'-dideoxythymidine (d4T)) were synthesized and their inhibitory activities were evaluated against wild-type and multidrug resistant HIV-1 RTs. Adenosine β-triphosphate (1) and AZT β-triphosphate (2) completely inhibited the DNA polymerase activity of wild type, the NRTI multi resistant, and nonnucleoside RT inhibitors (NNRTI) resistant HIV-1 RT at 10nM, 10 and 100 μM, respectively.

Abstract
An efficient route to the preparation of 5-substituted 2-amino-7-((2R,4R,5R)-tetrahydro-4-hydroxy-5-(hydroxymethyl)furan-2-yl)-3H-pyrrolo[2,3-d]pyrimidin-4(7H)-one compounds has been developed by the condensation of omega-substituted aldehydes with 2,6-diaminopyrimidin-4(3H)-one, followed by Boc protection to afford the corresponding N(2),N(2),N(7)-tris-Boc-O(4)-t-Bu-5-substituted 2-amino-3H-pyrrolo[2,3-d]pyrimidin-4(7H)-one, which is amenable to direct condensation with 1-chloro-2-deoxy-3,5-di-O-p-toluoyl-alpha-D-erythro-pentofuranose. This route affords an efficient synthesis to 2-amino-3H-pyrrolo[2,3-d]pyrimidin-4(7H)-one, 2-amino-5-alkyl-3H-pyrrolo[2,3-d]pyrimidin-4(7H)-one, and guanine nucleosides.

Abstract
Pyrosequencing is a method used to sequence DNA by detecting the pyrophosphate (PPi) group that is generated when a nucleotide is incorporated into the growing DNA strand in polymerase reaction. However, this method has an inherent difficulty in accurately deciphering the homopolymeric regions of the DNA templates. We report here the development of a method to solve this problem by using nucleotide reversible terminators. These nucleotide analogues are modified with a reversible chemical moiety capping the 3'-OH group to temporarily terminate the polymerase reaction. In this way, only one nucleotide is incorporated into the growing DNA strand even in homopolymeric regions. After detection of the PPi for sequence determination, the 3'-OH of the primer extension products is regenerated through different deprotection methods. Using an allyl or a 2-nitrobenzyl group as the reversible moiety to cap the 3'-OH of the four nucleotides, we have synthesized two sets of 3'-O-modified nucleotides, 3'-O-allyl-dNTPs and 3'-O-(2-nitrobenzyl)-dNTPs as reversible terminators for pyrosequencing. The capping moiety on the 3'-OH of the DNA extension product is efficiently removed after PPi detection by either a chemical method or photolysis. To sequence DNA, templates containing homopolymeric regions are immobilized on Sepharose beads, and then extension-signal detection-deprotection cycles are conducted by using the nucleotide reversible terminators on the DNA beads to unambiguously decipher the sequence of DNA templates. Our results establish that this reversible-terminator-pyrosequencing approach can be potentially developed into a powerful methodology to accurately determine DNA sequences.

Abstract
A beta-triphosphitylating reagent was subjected to reaction with aminomethyl polystyrene resin-bound p-acetoxybenzyl alcohol to yield the corresponding polymer-bound beta-triphosphitylating reagent. The solid-phase reagent was reacted with unprotected nucleosides (e.g., 3'-azido-3'-deoxythymidine, cytidine, thymidine, uridine, inosine, or adenosine) in the presence of 1H-tetrazole. Polymer-bound nucleosides underwent oxidation with t-butyl hydroperoxide, deprotection of cyanoethoxy groups with DBU, and the acidic cleavage, respectively, to afford only monosubstituted 5'-O-beta-triphosphorylated nucleosides.
