Applications of 4779-31-1
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Intermediates | Used as a protecting group in the synthesis of antiviral agents (e.g., HIV protease inhibitors) and peptide-based drugs | Applied in solid-phase or solution-phase peptide synthesis as a dual protecting group for the side-chain carboxyl and α-carboxyl groups of aspartic acid; deprotection achieved via hydrogenolysis to remove both benzyloxycarbonyl (Cbz) and benzyl (Bn) groups |
| Peptide Synthesis | Selective protection of the α- and β-carboxyl groups of aspartic acid to enable directional coupling | Amide bond formation conducted using coupling reagents such as DCC/HOBt or DIC/Oxyma; subsequent deprotection performed via Pd/C-catalyzed hydrogenolysis or TFA/Sc(OTf)₃ treatment |
| Biochemical Research | Preparation of structurally defined aspartic acid-modified peptide segments for enzyme substrate specificity studies or protein–protein interaction probes | Introduced as a pre-protected monomer in Fmoc-SPPS strategies to support high-purity, high-yield linear peptide chain assembly |
