Furan derivatives. ЬХХП. Synthesis and some properties of l-(5-nitro-2-furyl)- -2- (5-aryl-2-furyl)ethylenes
Wittig reaction has recently been applied also in the preparation of 5-nitrofuran derivatives of ethylene [1—5]. The quoted syntheses were accomplished starting either from 5-nitrofurfuryl halides which were converted into 5-nitrofurfurylidenephosphoranes and subsequent condensation of the latter with carbonyl compounds [1—4], or the intermediate phosphoranes were prepared from other furfuryl h...
متن کاملSynthesis and antimicrobial evaluation of some 6-aryl-5-cyano-2-thiouracil derivatives.
A series of 6-aryl-5-cyano-2-thiouracil derivatives (1a-d) was synthesized by the reaction of ethyl cyanoacetate with thiourea and aldehydes. These products were used as intermediate compounds for the synthesis of a number of thiouracil derivatives (2a-d to 10a-d). All compounds were screened for antibacterial and antifungal activities. Some of the prepared compounds, 6-(4-fluorophenyl)-4-oxo-2...
متن کاملSynthesis, Characterization and Study of Some N-Substituted Aryl-2- ({4-[(Substituted Aryl Carbamoyl) Methyl]-5-(Pyridin-4-yl)-4H-1, 2, 4-Triazol-3-yl} Sulfanyl) Acetamide
Pathogenic infections and inflammation are very common ailments humans suffer. Upsurge of resistant pathogens has impeded the antimicrobial drug development process in recent years and the search of new antimicrobial agents is clearly evident from the literature. In line with these developments the synthesis of N-substituted aryl-2-({4-[(substituted aryl carbamoyl) methyl]-5-(pyridin-4-yl)-4H-1...
متن کاملGreen synthesis and evaluation of 5-(4-aminophenyl)-4-aryl-4H-1, 2, 4-triazole-3-thiol derivatives
The green synthesis of 5-(4-aminophenyl)-4-aryl-4H-1,2,4-triazole-3-thiol was achieved in four steps, In first step, 4-amino benzoic acid refluxed in ethanol along with catalyst Conc. Sulphuric acid to produce ethyl-4-amino benzoate I. Further compound I refluxed with hydrazine hydrate in ethanol to produce 4-amino benzohydrazide II. Compound II refluxed in ethanolic potassium hydroxide with ca...
متن کاملSYNTHESIS AND ANTIMICROBIAL ACTIVITY OF 3-(2’-n-BUTYLBENZOFURAN-3’-YL)-5-ARYL-4, 5-DIHYDRO-1H-PYRAZOLES.
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...
