Isoquinoline Promoted Synthesis of alkyl 2-(1-alkyl-5-oxo-3-phenyl-2-thioxotetrahydro-4H-imidazol-4-yliden) acetate derivatives
Derivatives of thiazolidinone ring systems are known to act as anti-HIV infections , analgesic, anti-bacterial, anti-convulsant, anti parasitic, potential anti-inflammatory and herbicidal agents. Due biological activities of thiazolidinones ring, several methods for their synthesis have been illustrated in literature. Imidazolidine-2-thiones were synthesized by the oxidative cyclization of 1-be...

متن کاملSynthesis, physicochemical and anticonvulsant properties of new N-[(4-arylpiperazin-1-yl)alkyl]-3-phenyl- and 3-(3-methyl-phenyl)-pyrrolidine-2,5-diones.
The series of N-[(4-arylpiperazin-1-yl)-alkyl]-3-phenyl- and 3-(3-methylphenyl)-pyrrolidine-2,5-diones [VIII-XXV] were synthesized and evaluated for anticonvulsant and neurotoxic properties. Initial anticonvulsant screening was performed in mice, using intraperitoneal (ip) maximal electroshock-induced seizures (MES) and subcutaneous pentylenetetrazole-induced (scPTZ) seizure threshold tests. Th...

N, N΄-3, 4-di(methylamino)-1, 2, 5-oxadiazole (1f) was prepared by dehydration of N, N΄-3, 4-di(methylamino)glyoxime (2f) in aqueous potassium hydroxid at 170-180 ˚C. Under similar conditions N, N΄-3, 4-di(benzylamino)-1, 2, 5-oxadiazole (1c) and N, N΄-3, 4-di(isopropylamino)...
متن کاملNovel and efficient synthesis of N,N-dialkylamino-O-alkyl-2-(1-methyl-2-oxopropylidene)phosphorohydrazido oximes. Part 3.
A novel and efficient method has been developed for the synthesis of N,N-dialkylamino-O-alkyl-2-(1-methyl-2-oxopropylidene)phosphorohydrazido oximes 5. The reactions involve the condensation of diacetylmonoxime and N,N-dialkylamino-O- alkylphosphorohydrazides in the presence of activated silica and give the corresponding target oximes in excellent yields under mild conditions.
