Synthesis of some new Betti bases via one-pot three-component reaction of β-naphthol, primary diamine and substituted aromatic aldehydes

Abstract

An efficient method is described for the synthesis of N,N`-bis-[(2hydroxy-napthalene-1-yl) (substituted phenyl)methyl]2,6-diamino pyridine derivatives by one pot three components reaction of β-naphthol, 2,6diaminopyridine and substituted aromatic aldehydes in ethanol without any catalyst .Many of the synthesized products have been characterized by melting point ,FTIR,1HNMR,13C NMR and mass spectral data
