The general process for synthesizing peptides on a resin starts by attaching the first amino acid, the C-terminal residue, to the resin. To prevent the polymerization of the amino acid, the alpha amino group and the reactive side chains are protected with a temporary protecting group. Once the amino acid is attached to … See more The side chains of many amino acids are reactive and may form side products if left unprotected. For successful peptide synthesis, these side … See more In the Boc/Bzl protection scheme, Boc protecting groups are used to temporarily protect the N alpha nitrogen groups of the amino acids and benzyl-based protecting groups provide more … See more In this protection scheme, the alpha nitrogen of the amino acids is protected with the base labile Fmoc group and the side chains are … See more As shown in the mechanism below, tert-butyl carbonium ions are formed during Boc-deprotection. These cations react further with nucleophiles, forming isoprene or tert-butyl adducts.
