glutaric acid, Schiff bases, bis(4-formylphenyl) glutarate , bis(4-(chlorocarbonyl)phenyl) glutarate.Abstract
In the present study, ( Schiff's bases 6a - 6e) and (new amids derivatives 6f - 6j) have been synthesized .
The glutaroyl chloride(2) has been prepared by the reacting of glutaric acid and thionyl chloride in presence of (DMF) . The new compound bis(4-formylphenyl) glutarate (3) has been Synthesized from reaction of one mole of glutaroyl chloride and two moles of 4-hydroxybenzaldehyde . Compound 4,4'-(glutaroylbis(oxy))dibenzoic acid (4) was Synthesized from one mole of glutaroyl chloride and two moles of 4-hydroxybenzoic acid, while compound bis(4-(chlorocarbonyl)phenyl) glutarate (5) was prepared from 4,4'-(glutaroylbis(oxy))dibenzoic acid and Thionyl chloride . Then Schiff's bases 6a - 6e that prepared from the reaction of compound no:3 and derivatives amine in EtOH. Amids 6f - 6j were synthesized from the reaction of previous acid chloride (5) and derivatives amine in py. and DMF . All the prepared compounds have been characterized as usual by the spectral methods (which including FT-IR , H-NMR (6a , 6d and 6i) besides TLC . Techniques and the melting points were recorded . Then the antibacterial studies were checked against two types of bacterial . we discovered that the compounds 6a, 6d, 6h, and 6i showed high growth against all bacteria of E_ coli and staphylococcus aureus basides psudomonas aeruginosa .
