Bioisosterism: 1,2,4‐Oxadiazole Rings

ChemMedChem, 2023
AbstractAlthough studies in drug discovery have gained momentum in recent years, the conversion of drugs in use today into less toxic derivatives with pharmacologically superior properties is still of great importance in drug research. Bioisosterism facilitates the conversion of drugs into derivatives that present more positive pharmacological and ...

Banana-shaped 1,2,4-oxadiazoles

Pramana, 2003
3,5-Disubstituted 1,2,4-oxadiazoles are a new type of liquid crystalline (LC) compounds with asymmetrical five-membered heterocycle as a central unit. They have a bent shape and are very convenient model-compounds for studying the dependence of the LC properties on the molecular design.

3,5‐Disubstituted‐1,2,4‐oxadiazoles and 4,5‐dihydro‐3,5‐disubstituted‐1,2,4‐oxadiazoles

Journal of Heterocyclic Chemistry, 1978
AbstractA series of 3,5‐disubstituted‐1,2,4‐oxadiazoles (2) were prepared from a mono‐ or dichlorophenyl‐substituted amidoxime and (i) an acid chloride, (ii) an isatoic anhydride, or (iii) a β‐keto ester. Although cyclizations of the same amidoximes with acetaldehyde gave 4,5‐dihydro‐5‐methyl‐substituted derivatives (5), that annulation procedure ...

3,3‐Dinitrobutyl‐1,2,4‐oxadiazoles

Journal of Heterocyclic Chemistry, 1980
AbstractThe syntheses of 3,5‐bis(3,3‐dinitrobutyl)‐1,2,4‐oxadiazole and a series of 3‐aryl‐5‐(3,3‐dinitrobutyl)‐1,2,4‐oxadiazoles were accomplished by treating 4,4‐dinitropentanoyl chloride with the appropriate amidoximes to yield the intermediate O‐(4,4‐dinitropentanoyl)amidoximes, which were dehydrated to the 1,2,4‐oxadiazoles.

Mass spectrometric analysis of 1,2,4‐Oxadiazoles and 4,5‐Dihydro‐1,2,4‐Oxadiazoles

Mass Spectrometry Reviews, 2004
Abstract1,2,4‐Oxadiazoles and 4,5‐dihydro‐1,2,4‐oxadiazoles are an interesting class of compounds because of their pharmacological and other properties. Although short descriptions of these compounds under mass spectrometric conditions exist, we thought it worthwhile to write a comprehensive review of this class of compounds.
