Synthesis, characterization and antimicrobial study of some new Cyclohexenone derivatives

A series of chalcones and its cyclohexenone derivatives derived from 6-methoxy-2-naphthaldehyde are described. The chalcones synthesized through Claisen-Schmidt condensation reaction were treated with ethylacetoacetate in presence of NaOH to get the cyclocondensed product ethyl-4-(aryl)-6-(6-methoxy-2-naphthyl)-2-oxo-cyclohex-3-ene-1-carboxylate. The synthesized compounds were characterized from elemental analysis and spectral data. Ethyl 4-(4-chlorophenyl)-6-(6-methoxy-2-naphthyl)-2-oxo-cyclohex-3-ene-1-carboxylate (4f) was studied by single crystal X-ray diffraction
