    Area of Science:

    • Organic Chemistry
    • Glycochemistry
    • Medicinal Chemistry

    Background:

    • Cerebrosides are vital glycosphingolipids involved in cellular processes.
    • Synthesis of cerebroside analogues is crucial for understanding their biological roles and developing therapeutics.

    Purpose of the Study:

    • To synthesize novel cerebroside analogues utilizing phenylserine precursors.
    • To characterize the regioselectivity of glycosidic bond formation during the synthesis.

    Main Methods:

    • Synthesis involved esterification, N-acylation, and reduction with sodium bis(2-methoxyethoxy)aluminum hydride (SMEAH).
    • Condensation with acetobromoglucose followed by deacetylation yielded the final analogues.
    • Mass spectrometry was employed for structural elucidation and confirmation of the glycosidic linkage.

    Main Results:

    • Successful synthesis of cerebroside analogues from DL-threo- and DL-erythro-3-phenylserines was achieved.
    • Mass spectrometry confirmed the regioselective formation of the glycosidic bond.
    • The glycosidic linkage was exclusively formed at the primary hydroxyl group of the synthesized analogues.

    Conclusions:

    • The synthetic route provides access to novel cerebroside analogues.
    • The study demonstrates precise control over glycosidic bond formation at the primary hydroxyl position.
    • These findings contribute to the development of targeted glycoconjugate synthesis.
