Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of beta-lactam antibiotics and other bioactive molecules. Its structure allows for selective functionalization, making it valuable in constructing complex cyclobutane-containing scaffolds. The cyano and ester groups enable further chemical transformations, such as hydrolysis, reduction, and cyclization reactions. Commonly employed in medicinal chemistry for building blocks in drug discovery programs targeting CNS disorders and antimicrobial agents. Also utilized in research settings for studying ring strain effects in small cyclic systems during reaction optimization.
