α-Methylhydrocinnamic acid (2-methyl-3-phenylpropionic acid, 2-benzylpropionic acid) is a cinnamic acid derivative. Its synthesis by the asymmetric hydrogenation of α-methylcinnamic acid has been reported. α-Methylhydrocinnamic acid, a short chain fatty acid derivative (SCFAD), has been reported to correct the cystic fibrosis transmembrane conductance regulator (ΔF508-CFTR) defect. Conformational studies of 2-methyl-3-phenylpropionic acid has been investigated by NMR spectroscopy. The enantiomers of 2-benzylpropionic acid has been reported to be synthesized using a lipase-catalyzed resolution. (S) (+)-2-methyl-3-phenylpropionic acid participates in the synthesis of optically active (R)-5-methyl-6-phenylhexanoyl azide. L-2-Methyl-3. phenylpropionic acid has been reported to be an inhibitor of carboxypeptidase A. Polymer-supported “Evans” oxazolidinone mediated solid phase asymmetric has been employed in the synthesis of (S)-2-methyl-3-phenylpropionic acid.
