Used in organic synthesis as an intermediate for pharmaceuticals and biologically active compounds. Its α,β-unsaturated carboxylic acid structure with a benzylamino group enables participation in conjugate addition reactions, making it valuable in constructing nitrogen-containing heterocycles. Commonly employed in the development of enzyme inhibitors and anti-inflammatory agents. Also serves as a building block in the preparation of peptide mimetics due to its amide and carboxylic acid functionalities. Its Z-configuration influences stereoselectivity in synthetic pathways, enhancing specificity in drug design.
