Synthesis of new 1, 8-dioxo-octahydroxanthene derivatives containing 4-thiazolidinone moiety containing 4-thiazolidinone moiety
A series of novel 1, 8-dioxo-octahydroxanthene derivatives containing 4-thiazolidinone framework (4a-f) were synthesized through a four-step reaction starting from the reduction of nitro derivatives of 1, 8-dioxo-octahydroxanthenes. The resulting aminoxanthenes converted to thiourea derivatives via their reaction with methyl isothiocyanate. The final products were synthesized through the re...
متن کاملSynthesis and Anticonvulsant Activity Evaluation of 3-alkoxy-4-(4- (hexyloxy/heptyloxy)phenyl)-4H-1,2,4 -triazole
A series of 3-alkoxy-4-(4-(hexyloxy/heptyloxy) phenyl)-4H-1,2,4-triazole was synthesized. The anticonvulsant effect and neurotoxicity of the compounds were calculated with maximal electroshock (MES) test and rotarod tests with intraperitoneally injected mice. Among the synthesized compounds, compound 3-heptyloxy-4-(4-(hexyloxy) phenyl)-4H-1,2,4-triazole (5f) was the most active one and also had...

متن کاملSynthesis and characterization of new heat-resistance polymers based on N- (4-carboxy phenyl) trimellitimide and aromatic diamines
Five new aromatic poly(amide-imide)s (5a-e) were synthesized by direct polycondensationreaction of N-(4-carboxy phenyl) trimellitimide (3) with five aromatic diamines (4a-e) by usingtriphenyl phosphite in N-methyl-2-pyrrolidone (NMP) and pyridine at solution containingdissolved CaCl2. All of the polymers were obtained in quantitative yields with inherentviscosities between 0.29-0.40 dL/g. The r...
متن کاملOne Step Synthesis of 6-Amino-5-Cyano-4-Phenyl-2-Mercapto Pyrimidine Using Phosphorus Pentoxide
A simple and efficient approach towards one step synthesis of 6-amino-5-cyano-4-phenyl-2-mercapto pyrimidine and its hydroxyl derivatives have been developed by three component condensation of aromatic aldehydes, malononitrile and thiourea/urea in presence of phosphorus pentoxide (Scheme 1).
