Synthesis, characterization, and biological activities of some new pyrazoline derivatives, derived from ethyl-2-(2, 3-dichloroanilido) acetohydrazide
A series of new 1-[(2, 3-dichloroanilinomalonyl)]-3-(N-2’-cyanoethyl-N-2, 3-dichloroanilino)-5phenyl pyrazoline have been synthesized in 48 to 77% yield, by the reaction of N-cinnamoyl-N-2’cyanoethyl-2, 3-dichloroaniline with Ethyl-2-(2,3-dichloroanilido) acetohydrazide. Pyrazolines are yellow, cream and brown color solids, having high melting points. Identity of these products has been establi...
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...
متن کاملSynthesis of some new testosterone derivatives fused with substituted pyrazoline ring as promising 5alpha-reductase inhibitors.
Condensation of 3beta-hydroxy-16-[(4-chlorophenyl)methylene]androst-5-en-17-one (1) with hydrazine hydrate in acetic acid afforded N-acetyl pyrazoline derivative 2, while condensation of 1 with semicarbazide afforded compound 3. Also, compound 1 was treated with hydrazine hydrate in absolute methanol or ethanol to afford the corresponding alpha-methoxy (4) and alpha-ethoxy (5) derivatives, whic...
متن کاملsynthesis and characterization of some new cyclometalated organoplatinum(ii) complexes containing phosphite ligand
در این تحقیق روشی جهت سنتز یک سری از کمپلکس های پلاتین (ii) حاوی لیگاند های دهنده ی فسفری شامل فسفیت و فسفین ارائه شده است. واکنش پیش ماده ی پلاتین (ii)،trans/cis- [ptcl2(sme2)2] ، با 2 اکی مولار از لیگاند p(oph)3در حلال بنزن کمپلکس1، cis-[ptcl2(p(oph)3)2] را تولید می نماید. جهت سنتز کمپلکس سایکلو متال فسفیتی، کمپلکس 1 با 1 اکی والان واکنشگر ptcl2 در حلال زایلن در شرایط رفلاکس زیر گاز آرگون م...
