Boc-Asp(OtBu)-OSu is a protected derivative of aspartic acid, featuring a tert-butyloxycarbonyl (Boc) group and an active ester (OSu) for coupling reactions. The Boc group protects the α-amino group, allowing for selective reactions at the carboxylic acid side. The sulfoxy group (OSu) enhances the compound’s reactivity, facilitating the formation of amide bonds with nucleophiles in peptide synthesis. This compound is useful in organic synthesis and peptide chemistry, enabling the construction of complex peptide sequences for pharmaceutical and research applications.
