A novel application of the highly stable niobium oxide phosphate (NbOPO4) as an efficient catalyst for the synthesis of beta-enamino ketones under solvent-free conditions is described. This protocol, exhibits attractive yields, short reaction periods, lower loading of catalyst and high chemoselectivity. (C) 2016 Elsevier Ltd. All rights reserved.
