Boc-D-Tyr(OtBu)-Aib-OH is a protected dipeptide used in peptide synthesis. The Boc (tert-Butoxycarbonyl) group protects the N-terminus of the D-tyrosine (D-Tyr) residue, preventing unwanted reactions during synthesis. The hydroxyl group on the D-tyrosine side chain is protected by an OtBu (tert-butyl) group, safeguarding it from reactivity until selective deprotection is desired. Aib (α-aminoisobutyric acid) is the second amino acid in the sequence, a non-natural amino acid known for inducing helical structures in peptides. The -OH at the C-terminus indicates a free carboxyl group, allowing for further peptide coupling. This compound is utilized to introduce D-tyrosine and Aib into peptides, with specific protections ensuring controlled and selective synthesis while incorporating structural constraints.
