Z-L-Glu(tBu)-OSu is a protected glutamic acid derivative in which the α-amino group is carbobenzyloxy (Z/Cbz) protected and the α-carboxyl functionality is converted to an N-hydroxysuccinimide ester (OSu), with the side chain retaining the γ-carboxyl group masked as a tert-butyl (tBu) ester. The molecule therefore bears a Z-protected amino group and an OSu-activated carboxyl group that can undergo acyl transfer chemistry, while the tert-butyl ester provides temporary protection for the glutamate side-chain carboxyl during peptide-coupling workflows. Z-L-Glu(tBu)-OSu is used as an amino-acid coupling intermediate for preparing glutamate-containing peptides and related amide linkages, and its OSu activation supports incorporation of the protected glutamate unit under conditions where chemoselective acylation is required.
