An intramolecular decarboxylative coupling reaction for the construction of 2-(1,3,4-oxadiazol-2-yl)aniline derivatives was developed from readily available isatins and hydrazides by virtue of electrochemistry. In this reaction, isatins were employed as amino-attached C1 sources, providing a variety of 2-(1,3,4-oxadiazol-2-yl)aniline derivatives with moderate to good yields.

An overexpression of the transmembrane ATP-binding cassette transporter G2 (ABCG2, BCRP) in cancer tissues is supposed to play a role in the multidrug resistance (MDR) of tumors resulting in an inefficient chemotherapy. Therefore, co-administration of sel

series of new triazolyl derived 1,3,4-oxadiazoles 7a–7l is synthesized with high yields by coppercatalyzed alkyne–azide cycloaddition reaction between a variety of substituted aryl/alkyl azides and 2-(5-phenyl-1,3,4-oxadiazol-2-yl)aniline. Structures of intermediates and the final compounds are confirmed by FTIR, 1H and 13C NMR, and Mass spectra. The synthesized compounds demonstrate moderate antibacterial activity and potent antifungal activity against the tested strains.

A visible-light-induced synthesis of 2,5-disubstituted 1,3,4-oxadiazoles from simple diketones and hydrazides with the assistant of the photocatalyst eosin Y catalyzed decarboxylation and cyclization under mild conditions has been discovered. The reaction tolerates a wide range of functional groups and gives a variety of valuable 1,3,4-oxadiazoles in moderate to good yields. Finally, a plausible reaction mechanism was proposed.

Treatment of substituted 2-aminobenzoyl hydrazides with orthoesters has been found to yield different products depending upon the type of orthoester employed.Equimolar quantities of orthoester and hydrazide yield 3-amino-4(3H)-quinazolinones, whereas utilization of a two-fold excess (or greater) of orthoester yields, in some cases, 3,4-dihydro-5H-1,3,4-benzotriazepin-5-ones as minor products in addition to N-imidate esters as major products.Treatment of hydrazides with trimethyl orthobenzoate yields substituted 5-(2-aminophenyl)-1,3,4-oxadiazoles and 3,4-dihydro-5H-1,3,4-benzotriazepin-5-ones.The steric bulk of the phenyl group in trimethyl orthobenzoate effects the formation of adduct at the β-nitrogen of the hydrazide which cyclized to the oxadiazole and benzotriazepinone products.In the aliphatic orthoester series, the formation of adduct to the aromatic amino group appears to be favored which gives rise to quinazolinone and benzotriazepinone products.
