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.

An exploratory chemical effort has been undertaken to develop a novel series of compounds as selective CB1 agonists. It is hoped that compounds of this type will have clinical utility in pain control, and cerebral ischaemia following stroke or traumatic head injury. We report here medicinal chemistry studies directed towards the investigation of a series of 1-substituted-indole-3-oxadiazoles as potential CB1 agonists. Crown Copyright
SYNTHESIS OF INDOLYL-CONTAINING 1,2,4-OXADIAZOLES BASED ON IMIDIC ESTERS OF THE INDOLE SERIES
Kelarev, V. I.,Karakhanov, R. A.,Gasanov, S. Sh.,Polivin, Yu. N.,Mikaya, A. I.
, p. 637 - 642 (2007/10/02)
The 1,3-dipolar cycloaddition of the N-oxides of nitriles, generated in situ from arylhydroxamoyl chlorides, with imidic esters of the indole series leads to 3,5-disubstituted 1,2,4-oxadiazoles containing indole fragments at position 5.
SYNTHESIS AND PROPERTIES OF AZOLES AND THEIR DERIVATIVES. 37. SYNTHESIS OF 3,5-DISUBSTITUTED 1,2,4-OXADIAZOLES CONTAINING INDOLE RADICALS

The 1,3-dipolar cycloaddition of nitrile N-oxides to indole nitriles yields 3,5-disubstituted 1,2,4-oxadiazoles containing an indole radical at the 5 position.Condensation of amidoximes with indole iminoesters hydrochlorides yields 1,2,4-oxadiazoles havin
