At the heart of peptide synthesis lies the challenge of forming stable amide bond formationsDicyclohexylcarbodiimide (DCC) and diisopropylcarbodiimide (DIC) are commonly used to prepare amides, esters and acid anhydrides from carboxylic acids.. This process typically involves activating the carboxyl group of one amino acid to react with the amino group of another. This is where coupling reagents come into play. These chemicals are designed to facilitate this crucial step, ensuring high yields and minimizing unwanted side reactions. Several classes of coupling reagents have been developed over the years, each with its own advantages and limitations.

Among the most commonly employed coupling reagents are those that generate activated esters, such as OBt esters. Reagents like BOP, PyBOP, and HBTU fall into this category and have found wide application in routine solid-phase peptide synthesis (SPPS) and solution-phase synthesis. These reagents are particularly effective for the coupling of N-protected amino acids, although their applicability can vary when dealing with larger peptides.
