Upstream Synthesis Route

(Fmoc-Cys-OSu)2 is a versatile reagent commonly used in chemical synthesis for the selective protection of cysteine amino acid residues. This reagent is particularly useful in peptide synthesis, where the presence of multiple cysteine residues requires temporary protection to prevent unwanted side reactions. By utilizing (Fmoc-Cys-OSu)2, chemists can effectively mask the thiol group of cysteine, allowing for the sequential assembly of complex peptides without interference.In addition to protecting cysteine residues, (Fmoc-Cys-OSu)2 is also employed in the functionalization and modification of peptides. The N-hydroxysuccinimide (NHS) ester group present in the reagent enables selective coupling reactions with primary amines, leading to the introduction of various functional groups or labels onto the cysteine residue. This versatility makes (Fmoc-Cys-OSu)2 a valuable tool in the synthesis of bioconjugates, peptide mimetics, and other structurally diverse compounds in chemical biology and medicinal chemistry research.
