Z-L-Ser(tBu)-OSu is a protected L-serine derivative in which the amino acid side chain bears a tert-butyl-protected hydroxyl and the carboxyl group is converted to an N-hydroxysuccinimide (OSu) ester, with a benzyloxycarbonyl (Z) protecting group on the amino functionality. The molecule contains a carbamate-linked Z group, a tert-butyl ether on the serine side-chain oxygen, and an activated ester at the carboxyl terminus that can undergo acyl transfer under appropriate conditions while the stereocenter corresponds to the L-configuration indicated in the name. Z-L-Ser(tBu)-OSu is used as an amino acid building block for peptide-related synthesis and for preparing serine-containing conjugates or labeled derivatives where an activated carboxyl group and protected side-chain hydroxyl are required to control chemoselectivity.
