Synthesis and Antimicrobial Properties of 1,3,4-Oxadiazole Analogs Containing Dibenzosuberane Moiety

New Thermally Stable Aromatic Polyimides Based on Aromatic Diamine ‎2,5-Bis(3-amino-4-methyl benzene)-1,3,4-oxadiazole (BAMO):‎ Synthesis and Characterization

In current study, the synthesis and characterization of novel thermally stable polyimides (PIs) containing an 1,3,4-oxadiazole moiety based on a diamine, i.e. 2,5-bis(3-amino-4-methyl benzene)-1,3,4-oxadiazole (BAMO), have been reported. The polymers were characterized using FT-IR and elemental analysis (CHN). Thermal and mechanical behaviours of the prepared PIs were studied by thermo-gravimet...

Synthesis and Antimicrobial Studies on New Substituted 1,3,4-Oxadiazole Derivatives Bearing 6-Bromonaphthalene Moiety

Synthesis and In Vitro Antimicrobial Evaluation of New 1,3,4-Oxadiazoles Bearing 5-Chloro-2-methoxyphenyl Moiety

A series of new 1,3,4-oxadiazole derivatives, 4(a-h), containing 5-chloro-2-methoxy benzohydrazide moiety were synthesized by the reaction of 5-chloro-2-methoxybenzoate with different aromatic carboxylic acids. These newly synthesized compounds were characterized by FT-IR, (1)H NMR, mass spectra, and also by elemental analysis. All the newly synthesized compounds were screened for their antibac...

One-pot synthesis of ferrocene-containing 1,3,4-oxadiazole derivatives from N-isocyaniminotriphenylphosphorane (Ph3PNNC), cyclic ketones and ferrocene carboxylic acid

Reactions of N-isocyaniminotriphenylphosphorane with a cyclic ketone in the presence of ferrocene carboxylic acid proceeded smoothly at room temperature and in neutral conditions to afford ferrocene-containing 1,3,4-oxadiazole derivatives in high yields. The reaction proceeded smoothly and cleanly under mild conditions and no side reactions were observed. The structures of the products were ded...

Synthesis and evaluation of antimicrobial activity of novel 1,3,4-oxadiazole derivatives

In attempt to find new pharmacologically active molecules, we report here the synthesis and in vitro antimicrobial activities of various novel 1,3,4-oxadiazole containing 5-phenyltetrazole. The Schiff bases were obtained by condensation 2-(5phenyl-1H-tetrazol-1-yl)acetohydrazide with various aromatic aldehydes. Cyclocondensation of Schiff’s bases with acetic anhydride results in 1,3,4-oxadiazol...
