Synthesis dipeptide

Dipeptides are produced by coupling amino acids. The amino group on one amino acid is rendered non-nucleophilic (P in eq) and the carboxylic acid group in the second amino acid is deactivated as its methyl ester. The two modified amino acids are then combined in the presence of a coupling agent, which facilitates formation of the amide bond: RCH(NHP)CO2H + R'CH(NH2)CO2CH3 → RCH(NHP)C(O)NH(CHR')CO2CH3 + H2O WebJan 20, 2024 · To further prove that no racemisation of the activated amino acids occurs during peptide synthesis in PC, diastereomeric dipeptide 5b′ and tripeptide 7a′ were …
