The side-chain Acm group is stable to TFA but can be removed with Hg(II) [1] or Ag(I) [2] to give cysteinyl peptides, or oxidatively with Tl(III) [3] or I 2 [4] to generate cystinyl peptides. Associated Protocols and Technical Articles Cleavage and

The Dpm group has increased stability compared to Trt, enabling selective removal of Mtt groups on the solid phase with dilute TFA without loss of Dpm groups. Furthermore, the Dpm group is removed by treatment with 95% TFA cleavage cocktails.

Fmoc-Cys(STmp)-OH is a novel new tool for the regioselective synthesis of multiple disulfide bridged peptides by Fmoc SPPS. The STmp group is stable to piperidine but is extremely easy to remove by mild thiolysis.

The side-chain tBu group is stable to TFA and iodine oxidation. Treatment with MeSiCl 3 /PhSOPh removes t -Bu and cyclizes in one step without scrambling existing disulphide bonds.

High purity Fmoc-protected amino acid for research and process production of peptides, with very low levels of dipeptide, free-amino acids and acetic acid impurities. The standard derivative for Fmoc SPPS of peptides containing Cys [1] .
