Manganese oxide nanoparticles supported on graphene oxide as an efficient nanocatalyst for the synthesis of 1,2,4-oxadiazoles from aldehydes

The easy synthesis of graphene oxide (GO)-supported manganese dioxide (MnO2) nanoparticles as a stable heterogeneous nanocatalyst (MnO2@GO) is described. This catalyst was investigated in the synthesis of 1,2,4-oxadiazoles from amido

One-pot synthesis of 3,5-diaryl substituted-1,2,4-oxadiazoles using gem -dibromomethylarenes

1,2,4-Oxadiazole is one of the most promising heterocyclic ring systems in medicinal chemistry. In the present paper, we report the method for an efficient one-pot synthesis of 3,5-diaryl substituted 1,2,4-oxadiazoles using a two-component reaction of gem-dibromomethylarenes with amidoximes in good yields. In this method, gem-dibromomethylarenes are used as benzoic acid equivalents for the efficient synthesis of aryl-substituted 1,2,4-oxadiazoles. It is anticipated that this methodology will have versatile applications in the practical syntheses of various molecules of both medicinal and material chemistry importance.

Copper-catalyzed direct synthesis of 1,2,4-oxadiazoles from amides and organic nitriles by oxidative N-O bond formation

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

Fragmentation of GW4064 led to a highly potent partial farnesoid X receptor agonist with improved drug-like properties

Abstract The ligand activated transcription factor farnesoid X receptor (FXR) is a crucial regulator of several metabolic and inflammatory pathways and its activation by agonistic ligands seems a valuable therapeutic approach for many disorders. Most known non-steroidal FXR agonists however, have limitations that hinder their clinical development and novel FXR ligands are required. Evaluation of the co-crystal structures of the widely used FXR agonist GW4064 and related compounds in complex with the FXR ligand binding domain indicated that their disubstituted isoxazole moiety is especially relevant for FXR activation. By investigation of GW4064-fragments missing the aromatic tail, we discovered a highly potent and soluble partial FXR agonist (14, ST-1892) as well as a fluorescent FXR ligand (15) as potential pharmacological tool.

A facile approach to synthesize 3,5-disubstituted-1,2,4-oxadiazoles via copper-catalyzed-cascade annulation of amidines and methylarenes

Various 3,5-disubstituted-1,2,4-oxadiazoles are smoothly formed via copper-catalyzed cascade annulation of amidines and methylarenes. This tandem oxidation-amination-cyclization transformation represents a straightforward protocol to prepare 1,2,4-oxadiazoles from easily available starting materials, with inexpensive copper catalysts and green oxidants. It has the advantages of atom- and step-economy, good functional group tolerance, as well as operational simplicity.

A metal-free tandem approach to prepare structurally diverse N-heterocycles: Synthesis of 1,2,4-oxadiazoles and pyrimidinones

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.
