karbala journal of pharmaceutical sciences, Volume 5, Issue 7, Pages 31-41

This search includes preparation p-methoxy benzoyl hydrazine (II2) from the reaction between p-methoxy ethyl benzoate (I1) with hydrazine haydrate with the existence of ethanol absolute , then they were converted to hydrazine derivatives with different substituents (III3-6) through the reaction with aromatic benzaldehyde with out using a solvent under thermal fussion . Compounds of 1,3-oxazepine-4,7-dione (IV7-10) have also been prepared by ring closer reaction through the treatment of the prepared hydrazones (III3-6) and maleic anhydride ,The structure of the synthesis compounds was confirmed by FT-IR and 1HNMR spectral data , as the physical means ,the biological activity was studied againt two types of bacteria.

Some derivatives of 1,3 oxazepine – Schiff bases have been synthesized by the reaction of some aromatic aldehydes with N-phenyl azo aniline to synthesis of the compounds ,2-(p-phenyl azo)-1,4-phenylene aniline(1-6) ,and these compounds (1-6) were reacted with phthalic anhydride to obtain derivatives of 1,3- oxazapine. The chemical structures of the products were characterized by (IR ,and 1H NMR) and biological activity for some of these compounds were studied against three kinds of bacteria

A new compounds of 2-amino-5-(m-nitro phenyl)-1,3,4-oxadiazole [1] and 2-amino -5- phenyl-1,3,4-oxadiazole[2], N[(o-hydroxy benzylidene-5-( phenyl-2-yl)-1,3,4-oxadiazole-2-amine][3] or N[(m-nitro benzylidene-5-(m-nitro phenyl-2-yl)-1,3,4-oxadiazole-2-amine][4], 2-(m-nitro phenyl) -3 (5-m-nitrophenyl)1,3,4-oxadiazole]-2-yl-thiazolidin-4-one [5], 2-(m-nitro phenyl) –tetrazolo-1-yl)- 5-(m-nitrophenyl )1,3,4-oxadiazole ] [6] , 5-(m-nitro phenyl)-2/-(m-nitrophenyl)-2-yl-2,3-dihydro-1,3-oxazpine-4,7-dione [7] , 4-hydrazino nicotinic acid [8], 1-phenyl-4-(nicotinoyl) thiosemicarbazide [9], and 3-hydrazino-5- (pyridyl )-1,2,4- Triazole-4-phenyl [11], 3-(p-N,N/ dimethyl amino benzylidene)- hydrazino -5- (pyridyl )-1,2,4- Triazole-4-phenyl [12], 4-(3-methyl pyrazol-5-one)- hydrazino -5- (pyridyl )-1,2,4- Triazole-4-phenyl [13], 4-(3,5-dimethyl pyrazol)- hydrazine-5- (pyridyl )-1,2,4- Triazole-4-phenyl [14], ethyl 4-bromo-phenoxy acetate [15], p-bromo pheno -aceto thiosemicabazone [16] ,2- amino-5-[(p-bromp phenoxymethylene)-1,3,4-thiadiazole [17], 2N( p-nitro benzylidene)-1,3,4-Thiadiazole -5- (p-bromo phenoxy methyl [1 8 ], 5 -(p-bromo phenoxy methyl) 2/-(p-nitro phenyl- 2-yl)-5,6-dimethyl-1,3-oxazpine-4,7-dione [19] or5-(p-bromo phenoxy methyl) 3-(p-nitro phenyl- 2-yl)-2,3-dihydro-1,3-oxazpine-4,7-dione [20] and imidazoline[21].
The chemical structures of these compounds were identified by FT-IR,H-NMR , Uv spectroscopy and the reaction time ,purity was checked by TLC with determining the melting points. Some of the new compounds were tested against four strains of bacteria ( Klebsiella Pneumoniae ,Pseudomonas aeuroginosa ,Staphylococcus Aureus and Bacillus subtilus ) comparing these activities with that of starting material
