| Outline of Final Research Achievements |
The most reliable and generally used method for preparation of oligopeptides is currently solid-supported synthesis, which requires excess monomers, excess dehydrating agents and protective group manipulations. We consider this classical method to be updated to circumvent its low atom economy, and design a novel method named ‘thiol-relay,’ which discharges only carbon dioxide along with construction of a peptide bond. First, we improved an access to the thiocarboxylic acid, a key function in thiol-relay method, by introducing a novel, easy-to-prepare, and easy-to-handle precursor. The basic concept of thiol-relay peptide synthesis was proven, and we also found some problems toward more practical use of this method.
