- A Chemical Strategy for Intracellular Arming of an Endogenous Broad-Spectrum Antiviral Nucleotide
-
The naturally occurring nucleotide 3′-deoxy-3′,4′-didehydro-cytidine-5′-triphosphate (ddhCTP) was recently found to exert potent and broad-spectrum antiviral activity. However, nucleoside 5′-triphosphates in general are not cell-permeable, which precludes

- The aqueous N-phosphorylation and N-thiophosphorylation of aminonucleosides
-
We demonstrate N-phosphorylation and N-thiophosphorylation of unprotected aminonucleosides in aqueous media. N-Phosphorylations using phosphoric chloride and N-thiophosphorylations using thiophosphoryl chloride were explored as functions of pH using 5′-amino-5′-deoxyguanosine as substrate. These reagents were compared to phosphodichloridate and thiophosphodichloridate ions, and the methodology was applied to other aminonucleosides. S-Alkylations of the nucleoside N-thiophosphoramidates were investigated as functions of pH and alkylating agent. the Partner Organisations 2014.

- A tractable and efficient one-pot synthesis of 5′-azido-5′- deoxyribonucleosides
-
Synthetic routes to 5′-azidoribonucleosides are reported for adenosine, cytidine, guanosine, and uridine, resulting in a widely applicable one-pot methodology for the synthesis of these and related compounds. The target compounds are appropriate as precursors in a variety of purposive syntheses, as the synthetic and therapeutic relevance of azido- and amino-modified nucleosides is expansive. Furthermore, in the conversion of alcohols to azides, these methods offer a tractable alternative to the Mitsunobu and other more difficult reactions.

Replacing the phosphodiester backbone of RNA with positively charged guanidinium linkages has been shown to enable RNA oligomers to overcome electrostatic repulsion and bind double-stranded DNA in a triplex with high affinity. Ribonucleotide monomers with

- General Approach to the Synthesis of Specifically Deuterium-Labeled Nucleosides
-
Starting from D-(-)-ribose, a set of synthetic routes sharing common intermediates has been developed and exemplified in -, -, -, (5'R)--, and (5'S)--N4-benzoylcytidine and, by deoxygenation, their corresponding 2'-deoxynucleosides.These syntheses provide convenient access to millimolar quantities of deuterium/tritium-labeled natural or unnatural nucleosides for direct use or automated oligonucleotide synthesis.
