Boc-Dap-OH Chemical Properties,Usage,Production

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.
