The Versatility of Small Peptide Architectures
One of the most significant breakthroughs is the realization that short peptide sequences that function as asymmetric catalysts can be designed with incredible specificity. Because they are easily synthesized from readily available amino acid residues, researchers can create vast libraries of potential candidates. This modularity allows for the development of peptide architectures and multifunctional catalysts that can be adapted for a wide variety of stereoselective transformations.
In my experience analyzing the literature, it becomes clear that peptides have been established as highly active organocatalysts. Their structural flexibility is a key asset; for instance, structurally flexible β-turn-containing peptide catalysts are frequently cited for their ability to provide the precise spatial orientation required for complex chemical reactions.
