Fmoc-L-Cys(Propargyl)-OH

Published on 22.11.2017

This alkyne-functionalized cysteine building block can be incorporated into peptides via the Fmoc strategy.

Subsequent copper-catalyzed azide-alkyne cycloaddition allows for a chemoselective and mild functionalization of peptides with azide-bearing ligation partners. One possible application is the glycosylation of peptides, including the fast incorporation of short-lived ¹⁸F-labelled carbohydrates.


Reaction between an S-propargyl-cysteine bearing peptide and an azido-functionalized D-galactose.
