WebApr 9, 2024 · Abstract. The results from the synthesis of peptides by Fmoc/SPPS on a 2-CTC resin and then lactamization in solution or solid phase for the preparation of cyclopeptides are presented. Both procedures allow the synthesis of the desired compounds in good to very good yield and with high cyclization efficiency for on-resin macrocyclization. WebJun 20, 2024 · Sieber resin is an attractive option if the peptide contains sterically bulky amino acids or alternative functionality at the C-terminus due to the limited steric bulk when compared to the Rink amide linker. Importantly, this linker is also sensitive to mildly acidic conditions, yielding a fully-protected peptide amide in solution.
