Boric acid has been used as a mild and efficient catalyst reaction promoter for the cyclocondensation of β-naphthol, formalin and aromatic amines to afford respective 2,3-dihydro-2-phenyl-1H-naphtho-[1,2-e] [1,3] oxazine derivatives. The remarkable advantages offered by this method are inexpensive and readily available catalyst, simple procedure, faster reactions, involved the nonchromatographic and high yield of products.
