This compound is the D-enantiomer of a protected form of glutamic acid, primarily used in peptide synthesis. The Boc (tert-butoxycarbonyl) group serves as a protective group for the amino functionality, while the OChex (cyclohexyl ester) group protects the carboxylic acid side chain of D-glutamic acid. This protection is crucial during the stepwise assembly of peptides to prevent unwanted side reactions. It is particularly valuable in solid-phase peptide synthesis (SPPS), where selective deprotection and coupling steps are required to build the peptide chain. The compound ensures the precise incorporation of D-glutamic acid into the desired peptide sequence, making it essential in the development of pharmaceuticals, bioactive peptides, and research applications involving peptide-based studies.
