Boc-D-Leu-OSu, with the CAS number 60111-76-4, is a chemical compound commonly used in peptide synthesis and bioconjugation. It is a derivative of leucine, an essential amino acid, and features a tert-butyloxycarbonyl (Boc) protecting group, which is widely employed to protect amine functionalities during chemical reactions. The "OSu" part indicates the presence of an N-hydroxysuccinimide (NHS) ester, which enhances the reactivity of the compound towards nucleophiles, making it useful for coupling reactions with amino groups in peptides or proteins. This compound is typically a white to off-white solid and is soluble in organic solvents such as dimethylformamide (DMF) and dimethyl sulfoxide (DMSO). Its stability and reactivity make it a valuable reagent in the field of organic chemistry and biochemistry, particularly in the synthesis of peptide-based therapeutics and in the development of bioconjugates for various applications in drug delivery and diagnostics. Proper handling and storage conditions are essential to maintain its integrity and reactivity.

Boc-D-Leu-OSu is an amino acid-containing building block. It has been used in the synthesis of peptide gastrin antagonists, as well as analogs of the peptide antibiotic gramicidin S.
