Polymers Containing 1, 3, 4-Oxadiazole Rings for Advanced Materials

open access: yesMemoirs of the Scientific Sections of the Romanian Academy, 2011
This paper presents the synthesis, properties and potential applications of new polymers containing 1, 3, 4-oxadiazole rings, tacking into account the requirements of the modern technologies. Two classes of polymers containing oxadiazole rings were approached: polyamides and polyimides.

1, 3, 4-Oxadiazole: A Versatile Compound With Potent Analgesic Activity

open access: yes
Oxadiazole is a heterocyclic ring with 5 members that has 1 oxygen atom, 2 nitrogen atoms, 2 double bonds, and 2 carbons. In furan, they are created by placing two methylene groups (=CH) for two nitrogen (-N=) atoms. The aromaticity was reduced by the substitution of these groups. There were four different isomer of oxadiazole that were identified: 1,3,

Tandem diazotization/cyclization approach for the synthesis of a fused 1,2,3-triazinone-furazan/furoxan heterocyclic system

open access: yesBeilstein Journal of Organic Chemistry
A straightforward protocol for the synthesis of a previously unknown [1,2,5]oxadiazolo[3,4-d][1,2,3]triazin-7(6H)-one heterocyclic system was developed. The described approach is based on tandem diazotization/azo coupling reactions of (1,2,5-oxadiazolyl ...

A Review On: Antifungal And Antibacterial Activity Of 1, 3, 4-Oxadiazole Derivatives

open access: yes
1,3,4-Oxadiazoles are five-membered heterocyclic compounds containing two nitrogen atoms and one oxygen atom. These versatile molecules exhibit a range of biological effects, including antibacterial, antifungal, and antiviral properties. Recent research has demonstrated that many 1,3,4-oxadiazole derivatives surpass the activity of existing antibiotics
