Author(s): N.V.Shitole, S.D.Soluke, M.S.Shingare

An efficient and simplified protocol for boric acid catalyzed solvent-free synthesis of â-enaminones derivatives under microwave irradiation is described. The remarkable advantages offered by this method are inexpensive and readily available catalyst, simple procedure, faster reactions and high yield of products.
