The Evolution of Peptide-Based Catalysis
The fundamental premise behind this field is the mimicry of enzymatic efficiency. Enzymes are nature’s master architects, and by utilizing short, synthetic sequences, researchers have successfully created tools that perform complex chemical transformations. Over the past decade, several peptides have been developed as effective asymmetric catalysts for a range of synthetically useful reactions. These systems rely on the precise spatial arrangement of functional groups, often dictated by the secondary structure of the backbone.
When we look at the literature, it is evident that folded peptides have proven to be a fertile area for discovery of catalysts for reactions in organic synthesis. By leveraging combinatorial chemistry and rational design, we can now access catalytic environments that provide exceptional stereo-, chemo-, and site-selectivity.
