Used as a key intermediate in the synthesis of biologically active compounds, particularly in pharmaceutical research. Its vinyl group allows for further functionalization via cross-coupling reactions or polymerization, making it valuable in the development of novel drug candidates. The azetidine ring serves as a saturated heterocycle that can improve metabolic stability and solubility in medicinal chemistry applications. Commonly employed in the construction of complex molecules where a constrained ring system with a nitrogen atom is required.
