What is the acetylation reaction of amines?
The acetylation / acylation of amines takes place when the acetyl group substitutes the active hydrogen atom(s) attached to the nitrogen atom of the amine. This can take place by the attack of acetyl chloride on ammines. This is an excellent example of nucleophilic acyl substitution.
What is the purpose of acetylation of amines?
Acetylation is often used to place an acetyl protecting group on primary or secondary amines to reduce their reactivity toward oxidizing agents or electrophiles. Acetamides are usually crystalline solids which can be a help in purification by recrystallization.
What are the 2 types of acetylation?
Acetylation occurs mainly on lysine and can be divided into histone acetylation and non-histone protein acetylation (7).
Acetyl protection of amines can be easily carried out with acetyl chloride (AcCl) in the presence of a base (ex. TEA or DIEA) with an appropriate solvent (ex. THF or DCM).
