Fmoc-Pro-Pro-Pro-Pro-Pro-OH

Supplier: Bachem Americas

For Fmoc-dipeptides Fmoc-Xaa-Gly-OH and Fmoc-Xaa-Pro-OH, which can be used as building blocks in Fmoc-SPPS, please see also the subfamily 'Fmoc-Dipeptide Building Blocks' in the 'Amino Acid Derivatives' section. Pseudoproline dipeptides and isoacyl dipeptides can be found in this section as well. In case of a strong tendency towards diketopiperazine formation during Fmoc-SPPS, Fmoc-dipeptides have been coupled even at the risk of a some epimerization.
