Designer peptides: A large reactivity difference was observed between two peptide O‐esters that can undergo peptideligation through an in situ O‐to‐S acyl shift. This observation allowed for the design of “one‐pot” N‐to‐C sequential peptide fragment condensation through kineticallycontrolledligation with more readily accessible peptide O‐esters.
phenolic ester mediated peptidesynthesis is an efficient and well established method, the same via totally unsubstituted phenyl ester is not preferred due to the extremely slow rate of aminolysis. We have investigated the scope of the unsubstituted phenyl ester as an intermediate in peptide bond formation and found that it may be useful for the design of chemoselectivepeptideligation when HOBt is used
