Used in organic synthesis as an intermediate for pharmaceuticals and agrochemicals, particularly in the development of pyridine-containing compounds. Its α,β-unsaturated ester structure makes it suitable for Michael addition reactions and cross-coupling reactions. Commonly employed in the preparation of biologically active molecules, including kinase inhibitors and anti-inflammatory agents. Also utilized in materials science for constructing functionalized polymers and ligands for metal catalysts. The tert-butyl ester group allows for easy deprotection under mild acidic conditions, enabling stepwise synthesis in complex molecule assembly.
