Sequence: (Fmoc-Cys-OtBu)₂

As the disulfide bond can be cleaved under mild conditions (e.g. with trialkylphosphines) cystine derivatives are highly economic educts for synthesizing Cys derivatives. The cystine derivatives of fluorophores (e.g. J-1175) or the pNA derivatives may be chosen as educts for synthesizing Cys substrates.

Precursor of Fmoc-Cys-OtBu which has been used in the synthesis of orthogonally protected lanthionines. Barany et al. employed Fmoc-Cys-OtBu in developing a side-chain anchoring strategy for the SPPS of peptide acids with C-terminal cysteine.
