Boc group protecting

WebIn Boc chemistry, some of the lysine sidechain protecting groups are benzyloxycarbonyl (Z), 2-chlorobenzyloxycarbonyl (2-Cl-Z) and Fmoc. The 2-Cl-Z protected derivative Boc-Lys (2-Cl-Z)-OH is the lysine derivative commonly used in peptide synthesis by Boc chemistry. WebPeptide synthesis. Coupling of two amino acids in solution. The unprotected amine of one reacts with the unprotected carboxylic acid group of the other to form a peptide bond. In this example, the second reactive group (amine/acid) in each of the starting materials bears a protecting group. In organic chemistry, peptide synthesis is the ...
