Catalyst / Surfactant Free Chemoselective Acylation of Amines in Water
Mandava V.B. Rao,
Chemoselective acylation of amines has been carried out in water under open air using acyclic or cyclic anhydrides
or benzoyl chloride in the absence of any acid or base catalyst or a surfactant. The alkyl or aryl amines including
primary or secondary amines, amino acids, diamines etc afforded the corresponding N-acyl derivatives in good yields. The
selective N-acylation was observed in the presence of -OH, -SH, -COOH or -COOEt group. Being a practical alternative
to the existing methods for selective acylation of amines the present methodology may find applications.
Keywords: Acylation, amines, anhydrides, water.
