N-α-Z-N-ε-Boc-L-lysine methyl ester is a protected lysine derivative in which the α-amino group is carbobenzyloxy (Z/Cbz) protected and the ε-amino side chain is tert-butoxycarbonyl (Boc) protected, while the carboxyl group is present as a methyl ester. The molecule therefore contains a Z-protected α-amide-forming nitrogen and a Boc-protected ε-amine, alongside the esterified carboxylate functionality, and it is specified as the L stereochemical form at the α-carbon. This amino acid ester bearing orthogonal protecting groups is used as a stepwise building block for peptide synthesis and for the preparation of lysine-containing peptide intermediates where controlled deprotection and chemoselective coupling are required.
