N,N-Di-tert-butoxycarbonyl-L-histidine丨CAS 20866-46-0

N,N-Di-tert-butoxycarbonyl-L-histidine is a protected amino acid widely used in peptide synthesis, pharmaceutical research, and organic chemistry. The dual Boc (tert-butoxycarbonyl) groups protect both the amino and imidazole side-chain functionalities of histidine, allowing for selective coupling reactions in solid-phase and solution-phase peptide synthesis. It serves as a key intermediate in the preparation of histidine-containing peptides, enzyme inhibitors, and bioactive molecules. Additionally, the compound is employed in medicinal chemistry to synthesize derivatives for drug discovery, as well as in chemical research to study histidine reactivity, peptide conformations, and protein-mimetic systems.

The compound provides several advantages due to its dual protection, stability, and versatility. The Boc groups prevent unwanted side reactions, enabling precise and efficient peptide chain elongation. Its stability under standard laboratory conditions allows for long-term storage and convenient handling, while its solubility in common organic solvents facilitates incorporation into various synthetic protocols. N,N-Di-tert-butoxycarbonyl-L-histidine also allows for selective deprotection under controlled acidic conditions, yielding free histidine for subsequent functionalization. These properties make it a highly valuable intermediate for synthesizing complex peptides and histidine derivatives with high yield and reproducibility.
