The Fmoc solid phase peptide synthesis protocol hinges on the selective removal of the Fmoc protecting group to expose the N-terminus for the next amino acid coupling. This deprotection is typically achieved using a mild base, such as piperidine in dimethylformamide (DMF), a process known as Fmoc deprotection protocol. The liberated amine then reacts with an activated Fmoc-protected amino acid derivative. The success of the coupling step is critical for efficient peptide chain elongationBoc versus Fmoc for Solid Phase Peptide Synthesis. Various coupling reagents, such as HBTU, HATU, or DIC/HOBt, are utilized to activate the carboxyl group of the incoming amino acid, facilitating amide bond formation.
