4-(Trifluoromethyl)-L-phenylalanine Chemical Properties,Uses,Production

Uses

4-fluoro-l-phenylalanine (fF), or 4-trifluoromethyl-l-phenylalanine were introduced inside the chain of peptides to enhances their antimicrobial activity..

Synthesis

diethyl 2-(acetylamino)-2-[4-(trifluoromethyl)benzyl]malonate

114872-59-2

82337-58-4

3832-75-5

Step 2: Diethyl 2-acetamido-2-(4-(trifluoromethyl)benzyl)malonate (LXII, theoretical amount 0.125 mol) was dissolved in acetone (400 mL) and 2 M aqueous NaOH solution (400 mL) was added. The reaction mixture was refluxed overnight and subsequently concentrated under reduced pressure to remove the solvent. The residue was dissolved in water and washed with hexane (3 x 400 mL). The aqueous phase was adjusted to pH=1 with acid and the precipitate was collected by filtration to afford 2-acetamido-3-(4-(trifluoromethyl)phenyl)propionic acid (LXIII) as a white solid (25.8 g, 93.7 mmol, 75% overall yield in two steps).
