Boc-L-Tyr(tBu)-OH Chemical Properties,Usage,Production

Chemical Properties

White powder

Uses

N-Boc-O-tert-butyl-L-tyrosine (Boc-L-Tyr(tBu)-OH) is used as pharmaceutical intermediate.

Application

Boc-Tyr(tBu)-OH is an important organic reagent that can be used as a building block for the synthesis of many organic compounds. This compound could be used as a starting material to synthesize TPE-Tyr. TPE-Tyr can undergo covalent crosslinking via the formation of dityrosine linkages by exploiting horseradish peroxidase (HRP)-catalyzed phenol polymerization in the presence of H2O2, thereby activating the AIE process and switching on fluorescence emission of TPE core motif[1].

reaction suitability

reaction type: Boc solid-phase peptide synthesis

Synthesis

O-tert-butyl-L-tyrosine (2.00 g, 8.42 mmol, 1.0 equiv.) and di-tert-butyl dicarbonate (2.20 g, 10.10 mmol, 1.2 equiv.) were dissolved in a mixture of THF (15 mL) and NaOH (1 N, 30 mL) and stirred at room temperature for 10 h. THF was removed under reduced pressure, and the pH of residual solution was adjusted to 3.0 with dilute hydrochloric acid and the crude product was extracted by ethyl acetate. The combined organic phases was washed with saturated brine (pH 3.0) and dried over anhydrous Na2SO4. The organic solvent was removed under reduced pressure and dried in a vacuum oven at room temperature overnight, affording (N-Boc-O-tert-butyl)-L-Tyr (Boc-O-tert-butyl-L-tyrosine) as a yellowish solid (2.64 g, 93%)[1].
