Nucleoside synthons and unusual oligonucleotides

G Gosselin, A Haikal, C Chavis

    Nucleic Acids Symposium Series
    |January 1, 1982
    PubMed
    Summary

    Researchers synthesized novel nucleoside synthons for creating modified oligonucleotides. This includes 2'-O-methylnucleosides and xylofuranosyladenine analogs, potentially useful as interferon mediators.

    Area of Science:

    • Organic Chemistry
    • Medicinal Chemistry
    • Molecular Biology

    Background:

    • Oligonucleotide synthesis typically relies on commercially available nucleoside building blocks.
    • Specialized applications require custom synthesis of nucleoside precursors with modified structures.
    • Rare nucleosides with altered sugar or base components necessitate tailored synthetic strategies.

    Purpose of the Study:

    • To report the preparation of two distinct series of nucleoside synthons.
    • To detail the synthesis of 2 -O-methylnucleosides.
    • To describe the synthesis of xylofuranosyladenine analogs and a potential interferon mediator, 2 ,5 -(xyloA)3.

    Main Methods:

    • Chemical synthesis of modified nucleoside precursors.
    • Preparation of 2 -O-methylated nucleoside synthons.
    • Synthesis of xylofuranosyladenine analogs and subsequent formation of the trimer 2 ,5 -(xyloA)3.

    Main Results:

    • Successful preparation of two series of novel nucleoside synthons.
    • Characterization of 2 -O-methylnucleosides.
    • Synthesis of xylofuranosyladenine analogs and the compound 2 ,5 -(xyloA)3.

    Conclusions:

    • The reported methods provide access to valuable nucleoside synthons for specialized oligonucleotide synthesis.
    • The synthesized xylofuranosyladenine analogs and trimer show potential for applications, such as interferon mediation.
    • This work expands the toolkit for creating complex nucleic acid structures with potential therapeutic applications.
