3-(2’-n-butylbenzofuran-3’-yl)-5-aryl-4, 5-dihydro-1H-pyrazoles (4a-4k) have been synthesized. The synthesized products have been assayed for their antimicrobial activity against Gram+ve,      Gram-ve bacteria and fungi. All the synthesized products were assigned with IR, 1HNMR, Mass Spectra, TLC, and elemental analysis. Some of the products showed moderate activi...

Diazocoupling reaction of curcumin with different diazonium salts of p-toluidine, 2-aminopyridine, and 4-aminoantipyrine in pyridine yielded the arylhydrazones 2a-c. Arylhydrazone of p-toluidine reacted with urea, thiourea, and guanidine nitrate to produce 5,6-dihydropyrimidines. Further reaction of 2a with 2,3-diaminopyrdine in sodium ethoxide solution yielded 1H-pyrido[2,3-b][1,4]diazepine de...

A series of pyrano[2,3-c]pyrazole derivatives of indole was synthesized by multi-component reactions using the conventional and microwave irradiation approach. Particularly valuable features of this method include high yield, broad substrate scope, shorter reaction times and straightforward procedure. Antimicrobial screening of the synthesized derivatives against eight human pathogens, namely B...

pyrazoles and isoxazoles are well-known important heterocyclic compounds that due to their participation in the structure of many drugs are very important. pyrazoles and isoxzaloes can be prepared by oxidation of pyrazolines and isoxazolines respectively. in this work, trans-3,5-dihydroperoxy-3,5-dimethyl-1,2-dioxalane (dhpdmdo)/nh4i has been used as a new, powerful, nearly green, effective and...
