Abstract: يتضمن هذا البحث تحضير مشتقات جديدة لنوعين من قواعد شف هما نوع وكذلك [XI]a - d والبايارازولون [X]a - d ومشتقات البايارازول، [XIII]a - d و[XII]a - d ونوع جميعها تحتوي على وحدةالايزوكزولين او البيرمدين باستعمال الجالكون [VII]a - d الكوينولين - مادة اساسية. | The work involves synthesis of new two types from Schiff bases ([IV]a - f , [V]a - f and [XII]a - d, [XIII]a - d), pyrazoles[X]a - d, pyrazolones[XI]a - d and quinolones [VII]a - d derivatives containing isoxazoline or pyrimidine unit starting with chalcones. 4 - Bromoacetophenone was reacted with 4 - hydroxybenzaldehyde, 4 - hydroxyacetophenone was reacted with 4 - bromobenzaldehyde and 3 - Aminoacetophenone was reacted with 4 - bromobenzaldehyde or 4 - N,N - dimethyl aminobenzaldehyde in basic medium to give four chalcone compounds by Claisen - Schemidt reaction. The chalcons [I]a - d was reacted with hydroxylamine hydrochloride to form isoxazolines [II]a - d, while, the chalcones type [I]c,d was reacted with thiourea to give pyrimidine - 2 - thiones [III]a,b in basic medium. The pyrimidine - 2 - thiones [III]a,b and isoxazolines [II]c,d reacted with 4 - or 3 - substituted benzaldehyde and coumarin to form Schiff bases[IV]a - f [V]a - f and quinoline derivatives[VII]a - d, respectively. On the other hand, compounds[II]a,b or [V]b,f were reacted with ethylchloroacetate in basic medium to get new ester compounds[VIII]a - d.The condensation of new ester[VIII]a - dwith hydrazine hydrate led to produce new acid hydrazide [IX]a - d. The later compound refluxed with 4 - substituted benzaldehyde in ethanol to give Schiff bases( [XII]a - d and [XIII]a - d) ,while the reaction of these acid hydrazides [IX]a - d with acetyl acetone and ethyl aceto acetate led to form pyrazoles[X]a - d and pyrazolones[XI]a - d,respectively. The synthesized compounds were characterized by melting points, C.H.N. analysis, FTIR, Mass and 1HNMR spectroscopy(of some of them). Some of the synthesized compounds have been screened for their antibacterial activities using two types of bacteria; E. Coli and Staph. Aureus. All the examined compounds did not show any biological activity towards E. Coli but some of them show activity towards Staph. Aureus.This work can be summarized by the following schemes :
