摘要
In conventional stepwise Fmoc solid phase peptide synthesis, diisopropylethylamine (DIEA) base-catalyzed acylation methods lead to considerable amounts of racemization of Fmoc-Cys(Trt) residues during the activation/coupling process. The epimerization can be reduced to a negligible degree, via. a base-free activation step.
