Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and biologically active compounds. Its α,β-unsaturated ester structure with a pyrrolidine substituent makes it valuable in conjugate addition reactions and heterocycle formation. Commonly employed in the development of kinase inhibitors and central nervous system agents due to its ability to mimic peptide bonds and participate in hydrogen bonding. Also utilized in the synthesis of agrochemicals and specialty polymers where controlled reactivity and solubility are required.
