description
Dbz is a novel linker for the synthesis of peptide thioesters by Fmoc SPPS . After Fmoc removal the resin is being acylated with the first amino acid and then peptide synthesis is carried out. Following chain assembly the resin is being activated by treatment with p-nitrophenyl chloroformate. TFA cleaves the fully deprotected peptide benzimidazolinone which can be converted to a thioester with aryl thiol or used directly in native chemical ligation.
