Abstract Premature stop codons are the result of nonsense mutations occurring within the coding sequence of a gene. These mutations lead to the synthesis of a truncated protein and are responsible for several genetic diseases. A potential pharmacological

A convenient and efficient method for the generation of the iminoxy radical through anodic oxidation was developed for the synthesis of 3,5-disubstituted 1,2,4-oxadiazoles fromN-benzyl amidoximes. The transformation proceeds through 1.5-Hydrogen Atom Transfer (1,5-HAT) and intramolecular cyclization. The process features simple operation, mild conditions, broad substrate scope and high functional group compatibility, and provides a facile and practical way for the preparation of 1,2,4-oxadiazoles.
NBS-mediated practical cyclization of N-acyl amidines to 1,2,4-oxadiazoles via oxidative N?O bond formation

A reaction involving an efficient NBS-mediated oxidative N?O bond formation has been established for the synthesis of 1,2,4-oxadiazoles from readily accessible N-acyl amidines. The features of this synthetic method include simplicity of operation, mild re

Herein, we report the first Cu-catalyzed one-step method for the synthesis of 1,2,4-oxadiazoles from stable, less toxic, and readily available amides and organic nitriles by a rare oxidative N-O bond formation using O2 as sole oxidant. This met
A convenient and mild method for 1,2,4-oxadiazole preparation: Cyclodehydration of O-acylamidoximes in the superbase system MOH/DMSO

Herein, we reported a general, convenient, and efficient synthesis of 3,5-disubstituted-1,2,4-oxadiazoles via cyclodehydration of O-acylamidoximes in the superbase system MOH/DMSO (M = Li, Na, K). Excellent isolated yields (up to 98%) were attained within

A metal-free one-pot approach to the diversity oriented synthesis of N-heterocycles, 1,2,4-oxadiazoles and 2,6 disubstituted pyrimidin-4-ones is described via carboxamidation of amidines with aryl carboxylic acids and aryl propargylic acids. The reactions occur at room temperature forming N-acylamidines which undergo tandem nucleophilic addition-deamination- intramolecular cyclisation to give the corresponding heterocyclic compounds in good to excellent yields. This one pot approach has led to the successful synthesis of the drug lead molecule, ataluren, 3-(5-(2-fluorophenyl)-1,2,4- oxadiazol-3-yl) benzoic acid in two steps. the Partner Organisations 2014.
