Syntheses of Anisomycin Derivatives
The structure of anisomycin has been determined by X-ray investigation4 and the absolute configuration was confirmed by chemical correlation.5 Anisomycin has attracted considerable synthetic interest, and several synthetic studies, derivative syntheses as well as total syntheses, have been reported.6 Especially, the synthesis of its analogues has revealed the structure-activity relationship of ...
متن کاملSynthesis and estimations of antimicrobial properties of novel pyrazoline derivatives
Chalcones are the condensation product of acetophenone in combination with aromatic aldehydes in the presence of strong base. Chalcones and their metal complexes having prominent role in modern coordination chemistry. These compounds possessing novel structural features, interesting spectral and magnetic properties, have been the subject of intensive research due to their importance in medical,...
متن کاملSynthesis, antibacterial and antifungal activity of some new pyrazoline and pyrazole derivatives.
A series of 2-pyrazolines 5-9 have been synthesized from α,β-unsaturated ketones 2-4. New 2-pyrazoline derivatives 13-15 bearing benzenesulfonamide moieties were then synthesized by condensing the appropriate chalcones 2-4 with 4-hydrazinyl benzenesulfonamide hydrochloride. Ethyl [1,2,4] triazolo[3,4-c][1,2,4]triazino[5,6-b]-5H-indole-5-ethanoate (26) and 1-(5H-[1,2,4]triazino[5,6-b] indol-3-yl...

متن کاملSynthesis and Antimicrobial Evaluation of some New Pyrazole, Pyrazoline and Chromeno[3,4-c]pyrazole Derivatives
Alguns novos derivados de pirazol-5-carbonitrila 8,9 e pirazol-5-carboxamida 13 foram sintetizados pela reação de cicloadição de nitriliminas 3,4 a α-cianocinamonitrilas 5a-f e α-cianocinamamida 12a,b, respectivamente. Por outro lado, a adição de 3,4 a α-cianocinamato de etila 14a-f leva à produção de derivados de 2-pyrazoline-5-carboxilato de etila, 15, 16. Também, a cicloadição de 3,4 à 3-cia...
