A new method was developed to construct a special amido bond in the presence of beta-cyclodextrin. This process is similar to peptide synthesis in organisms. NMR experiments were performed to investigate the possible mechanism. This work has potential application in biomimetic peptide synthesis.[Supplementary materials are available for this article.
