Chompound contaning oxadiazole derivatives and their potential therapeutic uses.
Abstract: Derivatives of oxadiazole or furadi azole rings constitute a significant class of heterocyclic substances. Oxadiazole is a heterocyclic, five-membered ring with two carbons, one oxygen atom, two nitrogen atoms, and two double bonds. They are produced by substituting two nitrogen (-N =) atoms for two methylene groups (= CH) in furan. The furan ring's aromaticity was significantly decreased by substituting these groups, resulting in a conjugated diene character. There were …

Use of NMR and Other Spectroscopy Techniques in Heterocyclic Oxadiazole Derivatives Studies: A Review
Abstract: It was possible to create a number of novel symmetrical 2,5-dialkyl-1,3,4-oxadiazoles with substituents including carboxymethylamino, isopropyloxycarbonylmethylamino, and bromine at the terminal positions of the alkyl groups. The multistep process that was devised used hydrazine hydrate, phosphorus oxychloride, and commercially available acid chlorides that varied in alkyl chain length and terminal substituent.Diisopropyliminodiacetate was an easy way to substitute the intermediate bromine-containing 2,5-dialkyl-1,3,4-oxadiazoles. This was followed by hydrolysis in an aqueous methanol …
