Abstract: We wish to report reaction of various carbamates and oxazolidinones with carboxylic acid anhydrides in the presence of Wells-Dawson heteropolyacid catalysis. The N-acylation was carried out in presence heteropolyacid catalyst and gave the corresponding N-acyl products in good yields under solvent-free, green conditions. In this acylation used of Carboxylic acids and anhydride as acylating agents.
Keywords: Wells-Dawson, Heteropolyacid, Acylation, carbamates, oxazolidinones
