What are protection of functional groups?

A protecting group or protective group is introduced into a molecule by chemical modification of a functional group to obtain chemoselectivity in a subsequent chemical reaction. It plays an important role in multistep organic synthesis.

How can we protect amines?

Carbamates are useful as protecting groups for amines, and the most commonly employed are -Boc, -Cbz, and -Fmoc. The -Cbz (carboxybenzyl) protecting group was first used by Max Bergmann and Leonidas Zervas in 1932 for the synthesis of peptides, and is sometimes abbreviated “-Z” in honor of Zervas.

Which functional group is found in an amine?

Amino acids
Amino acids are organic molecules that contain an amine functional group (–NH2), a carboxylic acid functional group (–COOH), and a side chain (that is specific to each individual amino acid).

Which of the following reagent is used for protection of amines?

SOCl2 / Pyridine.

How can we protect secondary amines?

A simple method for chemically differentiating primary and secondary amines is described in which the primary amine is condensed with benzaldehyde to form an imine leaving the secondary amine available to be protected with BOC. The imine is then hydrolyzed to provide the free primary amine.

What are the qualities of a good protecting group?

Protecting groups are used in synthesis to temporarily mask the characteristic chemistry of a functional group because it interferes with another reaction. A good protecting group should be easy to put on, easy to remove and in high yielding reactions, and inert to the conditions of the reaction required.

What is the role of protective groups in protein synthesis?

Side chain protecting groups are known as permanent protecting groups, because they can withstand the multiple cycles of chemical treatment during the synthesis phase and are only removed during treatment with strong acids after synthesis is complete.
