WebIn 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 permanent protection of sidechains. Boc and benzyl-based protecting groups are both acid labile, so Boc/Bzl is not a true orthogonal protection scheme. WebJun 24, 2014 · Ornithine use same side chain protecting group like lysine. 2,3-Diaminoproanoic acid and 2,4-diaminobutanoic acid sie chain are often protected with Boc group, The Dde group can be utilized to protect the side chains of these amino acids, but precautions must be taken to prevent migration of the protecting group to the alpha …
