This chemical is primarily utilized in organic synthesis as a building block for the preparation of complex molecules, particularly in pharmaceutical research. Its N9-BOC protection group makes it a valuable intermediate in peptide synthesis, where it helps in the stepwise construction of peptides by preventing unwanted reactions at the nitrogen site. Additionally, it finds application in the development of spirocyclic compounds, which are often explored for their potential biological activities, including as enzyme inhibitors or receptor modulators. Its structural rigidity and functional group compatibility make it a versatile tool in medicinal chemistry for designing drug candidates with specific target interactions.
