Split-and-pool Synthesis and Characterization of Peptide Tertiary Amide Library

Overview

This article describes a synthetic method for creating peptide tertiary amides (PTAs), a class of peptidomimetics. The method combines split-and-pool and sub-monomer strategies to generate a one-bead one-compound library of PTAs.
