Z-Asp(OtBu)-OMe is a protected aspartic acid derivative featuring an aspartate side chain bearing a tert-butyl ester (Asp(OtBu)) and a benzyloxycarbonyl (Z) protecting group on the α-amino functionality, with the carboxyl terminus converted to a methyl ester (OMe). The molecule contains both the Z-carbamate and ester carbonyls, which mask the free amino and carboxyl groups to control chemoselectivity during stepwise assembly of peptide frameworks, while the tert-butyl ester on the side chain provides orthogonal protection relative to the α-carboxyl methyl ester. Z-Asp(OtBu)-OMe is employed as an amino acid building block for peptide synthesis and for preparing aspartate-containing intermediates where protected functional-group patterns are required for controlled coupling and downstream deprotection strategies.
