The syntheses of four selenonucleosides, namely 4′-β-selenoadenosine, -cytidine, -thymidine, and -uridine are described. Commercially available d-ribonolactone was converted to the key intermediate 1,4-anhydro-4-seleno-d-ribitol in seven steps in overall excellent yield. Oxidation of the seleno-d-ribitol with MCPBA gave a single diastereomeric selenoxide in excellent yield, which upon Pummerer reaction in the presence of silylated purine or pyrimidine bases gave stereoselectively the corresponding 4′-β-selenonucleosides. The stereochemistry at the anomeric center was determined by means of 1D-NOE experiments.
RIBONUCLEIC ACIDs WITH 4'-THIO-MODIFIED NUCLEOTIDES AND RELATED METHODS

, (2014/10/04)
Disclosed are messenger RNA molecules and related compositions incorporating a 4'-thio modification in the furanose ring of at least one nucleotide residue, and methods of using these mRNAs to produce an encoded therapeutic protein invivo and to treat or prevent diseases or disorders. In certain embodiments, the 4'-thio modified mRNA provides for enhanced stability and/or reduced immunogenicity in in vivo therapies.
