  An Access to the β-Anomer of 4′-Thio-C-ribonucleosides: Hydroboration of 1-C-Aryl- or 1-C-Heteroaryl-4-thiofuranoid Glycals and Its Regiochemical Outcome

  摘要：

  We have developed a novel method for the synthesis of the beta-anomer of 4'-thio-C-ribonucleosides from 3,5-O-(di-tert-butylsilylene)-4-thiofuranoid glycal. Palladium-catalyzed coupling of 1-tributylstannyl-4-thiofuranoid glycal with iodobenzene or a heteroaryl halide gave 1-C-phenyl- or 1-C-heteroaryl-glycals. Hydroboration of these glycals proceeded at the alpha-face, and subsequent alkaline hydrogen peroxide treatment of the resulting 2'-alpha-borane furnished the respective beta-anomer of 4'-thio-C-ribonucleosides. These results demonstrate that this synthetic method has a wider scope in terms of heterocyclic base structure. During this study, unexpected Markovnikov-oriented hydroboration has been observed to lead to the respective 1'-alpha-boranes. These 1'-boranes were converted into either the ring-opened structure or the 2'-deoxy derivatives depending upon their stability.

  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.
