Used as a key intermediate in organic synthesis, particularly in the preparation of complex pharmaceutical compounds. Its strained cyclopropyl core combined with the silyl-protected alkyne functionality allows for selective cross-coupling reactions, making it valuable in the construction of bioactive molecules. Commonly employed in medicinal chemistry for the development of kinase inhibitors and other targeted therapies. The tert-butylcarbamate (Boc) group enables easy protection and deprotection of amines during multi-step syntheses, enhancing its utility in peptide and heterocycle chemistry.
