Preparation of 1,3,4-oxadiazoles and 1,3,4-thiadiazoles via chemoselective сyclocondensation of electrophilically activated nitroalkanes to (thio)semicarbazides or thiohydrazides

[Figure not available: see fulltext.] Unusual reaction proceeding via the electrophilic activation of nitroalkanes in the presence of polyphosphoric acid has been discovered. Subsequent nucleophilic attack with semicarbazides or thiosemicarbazides allows

TiCl4 mediated facile synthesis of 1,3,4-oxadiazoles and 1,3,4-thiadiazoles

An efficient method for the synthesis of 2,5-disubstituted 1,3,4-oxadiazoles and 1,3,4-thiadiazoles has been developed. Various hydrazides or thionyl hydrazides readily react with DMA derivatives in the presence of TiCl4 as a catalyst to afford the desired products. This protocol provides a simple and economical procedure that affords the target products with good yields and wide substrate scope.

Preparation method of 1, 3, 4-thiadiazole compound and compound prepared by preparation method

A KHSO4 promoted tandem synthesis of 1,3,4-thiadiazoles from thiohydrazides and DMF derivatives

An efficient, simple and environmentally benign method for the construction of 1,3,4-thiadiazole skeletons via the tandem coupling and cyclization of thiohydrazides with DMF derivatives in the presence of KHSO4 has been reported. This method re

Transition-metal-free oxidative iodination of 1,3,4-oxadiazoles

Transition-metal-free oxidative iodination of 2-substituted 1,3,4-oxadiazoles was achieved by using sodium iodide as the halide source and Selectfluor as the oxidant. Variously substituted products were obtained in moderate to good yields under operationa

Multinuclear magnetic resonance studies of 2-aryl-1,3,4-thiadiazoles

The 1H, 13C and 15N spectra of aryl-substituted 1,3,4-thiadiazoles were recorded. The results obtained were correlated with Hammett coefficients. The experimental results were compared with DFT-calculated chemical shifts.

Greener and rapid access to bio-active heterocycles: one-pot solvent-free synthesis of 1,3,4-oxadiazoles and 1,3,4-thiadiazoles

A novel one-pot solvent-free synthesis of 1,3,4-oxadiazoles and 1,3,4-thiadiazoles by condensation of acid hydrazide and triethyl orthoalkanates under microwave irradiations is reported. This green protocol was catalyzed efficiently by solid supported NafionNR50 and phosphorus pentasulfide in alumina (P4S10/Al2O3) with excellent yields.
