Automated Fmoc-Based Solid-Phase Synthesis of Peptide Thioesters with Self-Purification Effect and Application in the Construction of Immobilized SH3 Domains
2-phenyl-isopropyl protecting groups. This approach solved the problems with methionine containing peptides and enabled the complete automation of the self-purifying synthesis of peptide thioesters. The study also addressed problems in the synthesis of difficult peptides. Aggregated truncation products can resist extraction and contaminate full-length thioesters obtained after TFAcleavage. It is shown that significant
