This compound, known as N-(tert-butoxycarbonyl)-cyclopropylglycine or Boc-Cpr-Gly-OH, is primarily utilized in organic synthesis as a key intermediate for preparing complex molecules, especially in the pharmaceutical industry for developing active pharmaceutical ingredients (APIs). Its structure features a cyclopropyl group attached to an α-amino acid scaffold with a carboxylic acid and a tert-butoxycarbonyl (Boc) protecting group on the nitrogen, making it a versatile building block for biologically active compounds. In peptide chemistry, it serves as a protected unnatural amino acid monomer, facilitating selective incorporation and reactions during peptide synthesis. It also supports research and development in novel chemical reactions and therapeutic agent discovery.
