acetylation of primary amine with acetic anhydride

How to acetylate primary amines and amino acids in brine solution?
The present methodology illustrates the efﬁcient acetylation of primary amines and amino acids in brine solution by means of acetyl chloride under weakly basic condition in the presence of sodium acetate and/or triethyl amine followed by trituration with aqueous saturated bicarbonate solution.
Are amines acylated by cyclic and acyclic anhydrides?
Amines are efficiently acylated by both cyclic and acyclic anhydrides in aqueous medium with sodium dodecyl sulfate (SDS) - without use of acidic or basic reagents. Various amines and anhydrides were reacted with equal ease. Chemoselective acylation in the presence of phenols and thiols has been achieved.
Is hydrotalcite a good catalyst for acylation of phenols and amines?
In conclusion, hydrotalcite has been found to be a highly efficient and low-cost basic catalyst for acylation of phenols, and amines in water at room temperature.
