Used as a key intermediate in organic synthesis, particularly in the preparation of cyclopropane-containing compounds that are valuable in pharmaceutical development. Its vinyl group enables participation in cross-coupling reactions and cycloadditions, allowing for the construction of complex molecular architectures. The tert-butyloxycarbonyl (Boc) protecting group stabilizes the amine functionality during multi-step syntheses and can be easily removed under mild acidic conditions, making it ideal for use in peptide-like and heterocyclic chemistry. Commonly employed in the synthesis of bioactive molecules, including antiviral and anticancer agents, where the strained cyclopropane ring contributes to enhanced metabolic stability and target binding affinity.
