Simple Preparation of N-Substituted 4-Arylpyrrolones.
eernpounds,2) This prompted us to devise a general synthetic method for N-substituted 4-arylpyrrolones. rv-Unsubstituted 4-(4-chlorophenyl)pyrrolone has been prepared from 4-bromo-3-(4-chlorophenyl)-2-butenoic acid with a largc excess ammonia water,i) However, the application of this method, using excess arnines in an aqueous so[ution, would be Iimited, rv-Substitutcd arylpyrrelones may be prep...

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 کاملSynthesis, antiviral, antituberculostic and antibacterial activities of some novel, 4-(4'-substituted phenyl)-6-(4"-hydroxyphenyl)-2-(substituted imino) pyrimidines.
A variety of novel 4-[(4'-substituted phenyl)-6-(4"-hydroxyphenyl)-2-substituted imino] pyrimidines were synthesized by reacting 4-(4'-substituted phenyl)-6-(4"-hydroxyphenyl)-2-aminopyrimidines with different substituted aromatic aldehydes, with coumarin and with chloroisatin. The 4-(4'-chlorophenyl)-6-(4"-hydroxyphenyl)-2-aminopyrimidines were synthesized by reacting 3-(4'-substituted phenyl)...
متن کاملDesign and Synthesis of Some Novel 4-(4-substituted aryl) Semicarbazones as Anticonvulsant Agents
In the present study, a series of 4-(4-substituted aryl) semicarbazones were synthesized from substituted anilines and subsequently evaluated for their anticonvulsant activities. The anticonvulsant activities were established by the anticonvulsant drug development (ADD) programme NIH, USA using experimental animal, adult male FCM mice (20-25 g) and adult Sprague-Dawley rats (100-150 g) and scre...
متن کاملPreparation and Characterization of Some Isoelectronic Boron-Nitrogen Analogs of Substituted Uracil [1]
Several l ,3,5-triaza-2-boracyclohexa-4,6-diones, which are isoelectronic analogs of substituted uracil, have been prepared by condensation reactions of boranes with biurets. They include species containing a N H or B H unit as potentially reactive sites. The latter are extremely sensitive to hydrolysis but are readily handled as the 2-methylaminoethanol derivative containing fourcoordinate boron.
