Opis:
A library of novel 3-(5-bromothiophen-2-yl)-6-phenyl-1,7a-dihydro-[1,2,4]triazolo[3,4-b][1,3,4]thiadiazole were synthesized in excellent yields via domino one-pot two component reactions of 4-amino-3-(5-bromothiophen-2-yl)-4,5-dihydro-1H-1,2,4-triazole-5-thiol and benzoic acid derivatives respectively. A triazolo-thiadiazole system may be viewed as a cyclic analogue of two very important components - thiosemicarbazide and biguanide which often display diverse biological activities. The significant advantages of this reaction include one-pot process, simple work-up procedure, excellent yields and no column chromatographic purification. All intermediates and final compounds were confirmed by 1H NMR, 13C NMR, Mass Spectroscopy methods and IR analysis.

Opis:
Coumarin-based triazoles were synthesized from 2-azido-N-phenylacetamide and terminal acetylenic compound by click chemistry. Whereas the CuSO4 used catalyts and sodium ascorbate used as a reducant affords only the favourable 1,4-regioisomer of triazole. Here DMF + t-BuOH + water used as a solvent.

Opis:
As heterocyclic compounds show good biological activity, we have synthesized nitrogen containing compounds among them 9a, 9c, 9e and 9f have shown very good antimicrobial activity with remarkable inhibition zones. N'-((5-chloro-3-methyl-1-phenyl-1H-pyrazol-4-yl)methylene)-5-methyl-1-phenyl-1H-1,2,3-triazole-4-carbohydrazide (9a-i, 10) was synthesized from 5-(aryloxy)-3-methyl-1-phenyl-1H-pyrazole-4-carbaldehyde and 5-methyl-1-phenyl-1H-1,2,3-triazole-4-carbohydrazide by condensation in acidic media. 5-(aryloxy)-3-methyl-1-phenyl-1H-pyrazole-4-carbaldehyde and 5-methyl-1-phenyl-1H-1,2,3-triazole-4-carbohydrazide were synthesized from phenyl hydrazine and substituted anilines respectively. All intermediates and final compounds were confirmed by 1H-NMR, 13C-NMR, Mass Spectroscopy methods and compound 9c was confirmed by single XRD analysis.

Opis:
A series of substituted 2-((phenyl amino)methyl)-1,2-dihydro-5-(3-methoxyphenyl)-1-phenyl-1,2,4-triazole-3-thione compounds were synthesized and examined their purities as per the literature. The IR spectra of νC=N, νC=S, νNH and νCOC frequencies and NMR chemical shifts (ppm) of δNH, δOCH3, δCH2, δC=N, δC=S, δOCH3 and δCH2 are also assigned. The assigned IR and both 1H NMR and 13C NMR spectral data have been correlated with Hammett substituent constants and Swain-Lupton’s parameters using single and multi-linear regression analysis. From the results of statistical analysis, the effect of substituents on the above spectral data has been studied.

An expeditious room temperature protocol for the synthesis of 1,4-disubstituted 1H-1,2,3-triazol-1-yl)methyl)-1H-benzo[d]imidazole from [3+2] cyclization by using 1H-benzo[d]imidazole azide and various substituted terminal alkynes and copper(I) as a catalyst. This synthetic approach has been various prominent features such as fewer reaction steps, Good Yield, simple reaction condition and no any further purification required. Characterizations of all the synthesized compounds were done by various spectroscopic techniques like FT-IR, NMR and Mass spectrometry. All the synthesized targeted compounds were screened and evaluated for their antimicrobial activities.
