1,3,4-Oxadiazole: A Biologically Active Scaffold

Mini-Reviews in Medicinal Chemistry, 2012
There has been considerable interest in the development of novel compounds with anticonvulsant, antidepressant, analgesic, anti-inflammatory, antiallergic, antipsychotic, antimicrobial, antimycobecterial, antitumour, antiviral and antitubercular activities. 1,3,4-oxadiazoles constitute an important class of compounds for new drug development. Therefore,

Thermally Activated Delayed Fluorescence in 1,3,4-Oxadiazoles with π-Extended Donors.

Journal of Organic Chemistry, 2020
Here, we describe the synthesis of five 1,3,4-oxadiazole-based donor-acceptor materials, using dendritic carbazole-based donors 9'H-9,3':6'9″-tercarbazole (terCBz) and N3,N3,N6,N6-tetra-p-tolyl-9H-carbazole-3,6-diamine (TTAC).

Aliphatic poly‐1,3,4‐oxadiazoles

Journal of Polymer Science Part A: General Papers, 1965
AbstractThree high molecular weight aliphatic polyoxadiazoles have been prepared by a new route from equimolar amounts of a diphenyl ester of dicarboxylic acid and an anhydrous hydrazine (or a dihydrazide). The resulting polymers have been characterized by microanalysis, intrinsic viscosity, x‐ray diffraction patterns, infrared absorption spectra, and ...

Recent progress of 1,3,4‐oxadiazoles as anticonvulsants: Future horizons

Archiv der Pharmazie, 2020
Epilepsy is the most common neurological disorder, which affects more than 50 million people worldwide. Despite the development and use of several antiepileptic drugs (AEDs), attempted seizure control fails in almost 30% of the individuals treated. Other

Novel syntheses of symmetrical 2,5-diaryl-1,3,4-oxadiazoles and 1,4-phenylenebis-1,3,4-oxadiazoles

Russian Chemical Bulletin, 1998
The reactions of trichloromethylarenes with excess hydrazine hydrate in ethanol gives symmetrical 2,5-diaryl-1,3,4-oxadiazoles in 68–96% yields. The reaction of 1,4-bis(trichloromethyl)benzene with acylhydrazines in an ethanol-pyridine mixture gives the corresponding substituted or unsubstituted 1,4-phenylenebis-1,3,4-oxadiazoles in 35–51% yields.
