| | Boc-Dap-OH Usage And Synthesis |
| Chemical Properties | White powder | | Uses | Reactant for:
- Protein assembly directed by synthetic molecular recognition motifs
- Solid phase synthesis of gramicidin S cyclic analogs with antibiotic and hemolytic activities
- Synthesis of HCV protease inhibitor modified analogs
- Solid phase synthesis of peptidic V1a receptor agonists
- Directed peptide assembly at lipid-water interface
| | Uses | (S)-3-amino-2-(tert-Butoxycarbonylamino)propionic acid (Boc-Dap-OH) is a derivative of amino acids, mainly used as an intermediate in organic synthesis and pharmaceutical chemistry, and can be used in the synthesis of peptide drug molecules and bioactive molecules. | | Preparation | The raw material was dissolved inabsolute ethanol (5 mL), and the reaction flask was immersed in a water bath at 25 C. To the alcoholicsolution, 10% palladium-carbon (22.9 mg) and 1,4-cyclohexadiene (10 equivalents with respect to4; 0.47 mL, 5.0 mmol) were added, and the mixture was allowed to react under magnetic stirringovernight. After filtration over a short pad of Celite 545, the solvent was evaporated under reducedpressure conditions, and the solid residue was partitioned in a 1:1 (v/v) H2O/EtOAc mixture (10 mL).The aqueous phase was separated, back extracted with EtOAc (3 10 mL), concentrated under reducedpressure conditions, and lyophilized.Finally, the target product Boc-Dap-OH is obtained.
| | Definition | Boc-Dap-OH is an amino acid molecule that is a zwitterion. Therefore, the addition of a base is required to prepare a nucleophilic amino acid. It is commonly acts as a nucleophile to attack the acyl carbon.
