Convergent Synthesis of Peptide Conjugates Using Dehydroalanines for Chemoselective Ligations
摘要:
Protein and peptide conjugates such as glycopeptides, prenylated peptides, and lipopeptides play essential roles in biology, A rapid and convergent entry into a variety of these compounds is described, The methodology involves the introduction of a dehydroalanine into peptides and subsequent chemoselective conjugate addition of an appropriate thiolate nucleophile, including farnesylthiolate or thioglycosides.

for the synthesis of dehydroalanineresidues (II) within peptides. The unnatural amino acid (Se)-phenylselenocysteine (I) can be incorporated into growing peptidechains via standard peptide synthesis procedures. Subsequent oxidative elimination affords a dehydroalanine at the desired position. The oxidation conditions are mild and tolerate functionalities commonly found in peptides, including variously
