  Application of Serine- and Threonine-Derived Cyclic Sulfamidates for the Preparation of S-Linked Glycosyl Amino Acids in Solution- and Solid-Phase Peptide Synthesis

  摘要：

  Cyclic sulfamidates were synthesized in 60% yield from L-serine and allo-L-threonine, respectively. These sulfamidates reacted with a variety of unprotected 1-thio sugars in aqueous bicarbonate buffer (pH 8) to afford the corresponding S-linked serine- and threonine-glycosyl amino acids with good diastereo-selectivity (greater than or equal to97%) after hydrolysis of the A sulfates. The serine-derived sulfamidate was incorporated into a simple dlipeptide to generate a reactive dipeptide substrate that underwent chemoselective ligation with a 1-thio sugar to afford an S-linked glycopeptide. This sulfamidate was also incorporated into a peptide on a solid support in conjunction with solid-phase peptide synthesis. Chemoselective ligation of a 1-thio sugar with the cyclic sulfamidate was achieved on the solid support, followed by removal of the N-sulfate. Finally, the peptide chain of the resulting support-bound S-linked glycopeptide was extended using standard peptide synthesis procedures.

  First regioselective ring opening of serine derived cyclic sulfamidate by hard nucleophiles like ArONa is developed, where β-elimination of serine sulfamidate ester by stronger nucleophiles is overcome by reversal of the electronic effect of the carboxylate anion. This method provides easy and direct access to a variety of N-Boc- and N-PMB protected β-aryloxy-α-amino acids with complete retention of enantiopurity in moderate to high yields.
