N-(tert-Butoxycarbonyl)-L-phenylalanine Usage And Synthesis

Chemical Properties	N-(tert-Butoxycarbonyl)-L-phenylalanine is white fine crystalline powder
Uses	N-(tert-Butoxycarbonyl)-L-phenylalanine is used in enantioselective hydrolysis of amino acid esters. Acts as an inhibitor of gastric acid secretion.
Uses	N-Boc-L-phenylalanine is a derivative of Phenylalanine used in enantioselective hydrolysis of amino acid esters.
Preparation	Sodium hydroxide (4.4 g, 0.11 mol) was placed in a flask, and dissolved in water (110 mL). Phenylalanine (16.5 g, 0.1 mol) was added, the suspension was stirred until a solution was obtained, and then tert-butanol (75 mL) was added. Boc2O (22.3 g, 0.12 mol) was then added with stirring over a period of 1 h, keeping the mixture near 0 ℃. A white precipitate was produced, and at the end of the addition the pH had dropped to 7.5–8.5. The mixture was then carefully acidified by the slow, continuous addition of saturated citric acid to give the product N-tert-butoxycarbonyl-L-phenylalanine (21.5 g, 81%); mp 85℃; [a]21D = t25:5 (c = 1, ethanol).
reaction suitability	reaction type: Boc solid-phase peptide synthesis reaction type: C-H Activation reagent type: ligand reaction type: Peptide Synthesis
