Synthesis and Identification Some of the Seven Memberd Ring Derivatives from Carboxylic Acid

The research was involved preparation of cyclic compounds which are containing of more than one hetero Atoms in their structures like(N)-nitrogen or(O) oxygen, in these work the first reacting 2-(4-isobutylphenyl) propanoic acid to change to the ethyl 2-(4-isobutylphenyl) propanoate the second reacting to change to the 2-(4-isobutylphenyl) propanehydrazide.Atom.Aseven-member ringcompounds were prepared By condensation of N-Ndi methyl amino benzaldehyde with(M2)To give(A1)) and condensation of 4-chloro salicylaldehyde with(M2) to /give(A2). These compound were found to react with maleic anhydride and phthalic anhydride and succinct anhydrideTo give 7-memberd ring (N1), (N2) and (Y1), (Y2) and (Y3). All these synthesized compound have been characterized by melting point elemental analysis FTIR and HMNR spectroscopy by their un corrected melting points,elemental analysis and FT-IR spectra
