Abstract
Cyclic acylurea readily formed from Dpr(Phoc) linker was shown to prov ide linkage that is fully compatible with standard Fmoc-based solid-ph ase peptide synthesis protocols. The utility of this linkage was check ed during Tyr-Asp-Pro-Ala-(Pro)(6)-OH synthesis which is very prone to diketopiperazine formation at the dipeptide stage. This side-reaction was avoided by maintaining the Dpr(Phoc) linker until the tripeptide stage, while piperidine had to be temporary replaced with morpholine a s reagent for Fmoc group removal.
