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...
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 کاملATTEMPTED PREPARATION OF N-SUBSTITUTED DIPHENYLCYCLOPROPENEIMINE N-OXIDE
The reaction of diphenylcyclopropenone with several N-substituted hydroxylamine and primary amines are investigated. Most of these reactions led to ring opened or ring enlarged products, instead of the desired N-Oxide or imine. The reaction of cyclopropeneimine with peracid-another possible route to N-substituted cyclopropeneimine N-Oxide is studied. Most of the unexpected products are ide...
متن کاملMicrowave assisted synthesis of N-arylheterocyclic substituted-4-aminoquinazoline derivatives.
A simple, efficient, and general method has been developed for the synthesis of various N-aryl heterocylic substituted-4-aminoquinazoline compounds from 4-chloro- quinazoline and aryl heterocyclic amines under microwave irradiation using 2-propanol as solvent. The advantages of the use of microwave irradiation in relation to the classical method were demonstrated.
متن کاملSynthesis and anticonvulsant activities of 4-N-substituted arylsemicarbazones.
A series of 4-N-substituted arylsemicarbazones with increased lipophilicity were synthesized and evaluated for anticonvulsant activity. The compounds provided significant protection against maximal electroshock induced seizures (MES) and seizures indicated by sc pentetrazole administration (sc PTZ) at 300 mg/kg after 0.5 h. The compounds 8 and 4 were active in MES and sc PTZ indicated seizure. ...
