Fmoc-based synthesis of peptide thioesters for native chemical ligation employing a tert-butyl thiol linker

Org Lett. 2011 Apr 1;13(7):1606-9. doi: 10.1021/ol1029723. Epub 2011 Feb 28.

Abstract

tert-Butyl thioesters display an astonishing stability toward secondary amines in basic milieu, in contrast to other alkyl and aryl thioesters. Exploiting this enhanced stability, peptide thioesters were synthesized in a direct manner, applying a tert-butyl thiol linker for Fmoc-based solid-phase peptide synthesis.
