The new asymmetrical organic ligand 2-{4-[(1H-imidazol-1-yl)methyl]phenyl}-5-(pyridin-4-yl)-1,3,4-oxadiazole (L, C17H13N5O), containing pyridine and imidazole terminal groups, as well as potential oxdiazole coordination si

The preparation, characterization and catalytic activity of Ni NPs supported on porous alginate-g-poly(p-styrene sulfonamide-co-acrylamide)

Herein, we report the synthesis of nickel nanoparticles under mild conditions using porous alginate-g-poly(p-styrene sulfonamide-co-acrylamide) as a protecting/stabilizing agent and sodium borohydride as a reducing agent. The porous cross-linked polymeric support was preparedviacombining the use of sol-gel, nanocasting, and crosslinking techniques, in which thep-styrene sulfonamide monomer (PSSA) andN,N′-methylene-bis (acrylamide) (MBA) cross-linker underwent copolymerization on the surface of sodium alginate in the presence of a SiO2nanoparticle (NP) template (Alg-PSSA-co-ACA). The prepared catalyst (Alg-PSSA-co-ACA@Ni) showed high catalytic activity for the one-step synthesis of 1,3,4-oxadiazoles from the reaction of hydrazides and aryl iodides through isocyanide insertion/cyclization.

I2-mediated oxidative C-O bond formation for the synthesis of 1,3,4-oxadiazoles from aldehydes and hydrazides

A practical and transition-metal-free oxidative cyclization of acylhydrazones into 1,3,4-oxadiazoles has been developed by employing stoichiometric molecular iodine in the presence of potassium carbonate. The conditions of this cyclization reaction also work well with crude acylhydrazone substrates obtained from the condensation of aldehydes and hydrazides. A series of symmetrical and asymmetrical 2,5-disubstituted (aryl, alkyl, and/or vinyl) 1,3,4-oxadiazoles can be conveniently generated in an efficient and scalable fashion.

Use of ester formylhydrazones for the synthesis of 1,2,4-triazole and 1,3,4-oxadiazole derivatives

A series of ester formylhydrazones were synthesised by the reaction of alkyl imidate hydrochlorides with ormylhydrazine. Treatment of the ester formylhydrazones with acetic acid hydrazide, isonicotinic acid hydrazide, nicotinicacid hydrazide, and 4-hydroxybenzhydrazide resulted in the formation of either 4-acylamino-4H-1,2,4-triazoles or 2,5-disubstituted 1,3,4-oxadiazoles. 3-Alkyl-4-amino-4,5-dihydro-1H-1,2,4-triazol-5-ones were synthesised by the reaction of the ester formylhydrazones with carbohydrazide. Some arylidenamino compounds were synthesized by the reaction of 4-amino-4,5-dihydro-1H-1,2,4- triazol-5-ones with several aldehydes. These compounds were characterised by elemental analyses, IR, 1H NMR, and UV spectral techniques.

Synthesis and biological screening of Some 1,3,4-oxadiazoles

Treatment of Schiff bases with yellow mercuric oxide and iodine in DMF medium yields the title compounds 1,3,4-oxadiazoles (4a-j). The structures of the newly synthesized compounds were assigned on the basis of IR, 1H NMR, Mass spectral data and elemental analysis. All the new compounds were evaluated for their in vitro antibacterial and antifungal activity. Some of the new compounds showed good activity against some bacteria when compared with the standard drug.
