Oxadiazoles in Medicinal Chemistry
Journal of Medicinal Chemistry, 2012Oxadiazoles are five-membered heteroaromatic rings containing two carbons, two nitrogens, and one oxygen atom, and they exist in different regioisomeric forms. Oxadiazoles are frequently occurring motifs in druglike molecules, and they are often used with the intention of being bioisosteric replacements for ester and amide functionalities.

Journal of Fluorine Chemistry, 1992
Abstract Some new polyfluorinated 1,3,4-oxadiazoles have been obtained via a two-step method. The cycloadditions of the 1,3,4-oxadiazoles have been studied and an analysis of the energies of the frontier orbitals calculated by the MNDO method indicates a LUMO-dependent pathway for cycloaddition.

Journal of Molecular Spectroscopy, 1967
Abstract The infrared absorption spectrum of 1,3,4-oxadiazole has been recorded in the region 5000-400 cm −1 in the vapor and in the liquid phases, in CS 2 and C 2 Cl 4 solutions. Also, the infrared absorption spectrum of liquid 2,5-dimethyl-1,3,4-oxadiazole was recorded in the same region. A tentative assignment of the fundamental vibrations of 1,

Poly‐1,3,4‐oxadiazoles. I. Polyphenylene‐1,3,4‐oxadiazoles
Journal of Polymer Science Part A: General Papers, 1965AbstractPolyphenylene‐1,3,4‐oxadiazoles have been prepared from benzenedicarboxylic acids or their derivatives and hydrazine by solution polycondensation in fuming sulfuric acid or polyphosphoric acid. These polymers were characterized by good thermal stability, and the molecular weights attained were high enough for the products to exhibit fiber‐or ...
