Resumen
The first examples of amino acid (Ser/Thr)-sp2-iminosugar glycomimetic conjugates featuring an α-O-linked pseudoanomeric linkage are reported. The key synthetic step involves the completely diastereoselective α-glycosylation of Ser/Thr due to strong stereoelectronic and conformational bias imposed by the bicyclic sp2-iminosugar scaffold. Mucin-related glycopeptides incorporating these motifs were recognized by the monoclonal antibody (mAb) scFv-SM3, with activities depending on both the hydroxylation pattern (Glc/Gal/GlcNAc/GalNAc) of the sp2-iminosugar and the peptide aglycone structure (Ser/Thr). © 2016 American Chemical Society.
