Microwave-Assisted Synthesis of Phenothiazine and Quinoline Derivatives
Application of a dynamic microwave power system in the chemical synthesis of some phenothiazine and quinoline derivatives is described. Heterocyclic ring formation, aromatic nucleophilic substitution and heterocyclic aldehydes/ketones condensation reactions were performed on solid support, or under solvent free reaction conditions. The microwave-assisted Duff formylation of phenothiazine was ac...
متن کاملMicrowave Assisted Synthesis, Characterization and Antimicrobial Activity of 10H-Phenothiazine Derivatives
A new environmental benign method for synthesis of phenothiazine derivatives using microwave irradiation has reported. A mixture of o-substituted aromatic amine and p-substituted phenol converted into biphenyl amine derivative using microwave irradiation. Further, thionation of biphenyl amines under same irradiation has provided the title phenothiazine derivatives. The later compounds then oxid...
متن کاملMicrowave Assisted Synthesis of Some Quinoxaline Derivatives
The high commercial demand for quinoxalines needs a rapid, greener and safer synthetic method among the chemists. A series of quinoxaline derivatives has been synthesized by condensation of diamines and dicarboniles in microwave heating conditions and in solvent free media. This environmentally benign synthetic approach gives us excellent yields (80-90%) in shorter reaction time (3.5 minutes.)....
متن کاملComparison of Conventional and Microwave-assisted Synthesis of Benzotriazole Derivatives
A green chemistry approach for organic synthesis is described here, which involves microwave exposure of reactants in presence or absence of solvents. A novel and simple method has been developed for the synthesis of some benzotriazole derivatives under microwave irradiation. In addition, these compounds were synthesised also by conventional heating procedures for comparison. All the compounds ...
متن کاملMicrowave-Assisted Synthesis of Potent Antimicrobial Agents of Flavanone Derivatives
The currently available antimicrobial drugs suffer from toxicity, interactions with other drugs, insufficient pharmacokinetic properties, and the development of resistance. Thus, development of new antimicrobial agents with optimum pharmacokinetics and low toxicity is important. In this study, a series of flavanone, hydrazone derivatives have been prepared from flavanone under microwave irradia...
