Engineering and Exploiting Immobilized Peptide Organocatalysts for Modern Synthesis

Molecules
Short- and medium-sized peptides have long been used as effective and versatile organocatalysts. In the early 80s, Inoue used diketopiperazines in the Strecker reaction, while Juliá and Colonna reported the epoxidation of chalcone catalyzed by poly-L-Ala.
