Boc-Tyr(OtBu)-Leu-OH is a protected dipeptide used in peptide synthesis. The Boc (tert-Butoxycarbonyl) group protects the N-terminus of the tyrosine (Tyr) residue, preventing it from reacting during the synthesis process. The hydroxyl group on the tyrosine side chain is further protected by a tBu (tert-butyl) group, ensuring that it remains unreactive until selective deprotection is needed. Leu (Leucine) is the second amino acid in the sequence, contributing hydrophobic properties. The -OH at the C-terminus indicates a free carboxyl group, allowing for further peptide bond formation. This compound is used to introduce tyrosine and leucine into peptides while maintaining control over the reactivity of the functional groups for precise and efficient synthesis.
