Synthesis of methyl 2-[2-(alkylimino)-4-oxo-3-phenyl-1,3-thiazolan-5-yliden]acetate derivatives under solvent-free condition
An efficient synthesis of Methyl 2-[2-(alkylimino)-4-oxo-3-phenyl-1,3-thiazolan-5-yliden]acetate derivatives via simple three-component reaction and one-pot reactions between isoquinoline, dimethyl acetylenedicarboxylate and N-phenylthiourea under solvent-free conditions without using any additional catalyst, is described. The mild reaction conditions and good yields and exhibit the synthetic a...
متن کاملIsoquinoline 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 and Study of Analgesic, Anti-inflammatory Activities of 3-methyl-5- Pyrazolone Derivatives
Considerable amount of research has been carried out in the field of pyrazolone derivatives due to their diverse biological, pharmacological and chemical properties. The need was felt to synthesize certain 3-methyl-5-pyrazolone derivatives with potent analgesic and anti-inflammatory activity and with lesser side effects as it had been proved of late that the beneficial effects of pyrazolones ou...
متن کاملSynthesis and Antimicrobial Activity of Some 2-[(4-Substituted-Phenyl-3-Chloro-Azetidin-2-One)-5-(2'-Methylamino-4-Phenyl-1', 3'-Thiazolyl-]-1, 3,4-Thiadiazoles
A new 2-[(4-substituted-phenyl-3-chloroazetidin-2-one)-5-(2'-methylamino 4-phenyl-1', 3'-thiazolyl-]-1, 3, 4-thiadiazoles, 5(a-n) were synthesized from 2-substituted-benzylideneamino-5-[2'-methylamino-4'-phenyl-1',3'-thiazolyl]-1,3, 4-thiadiazole, 4(a-n) using 2-amino-4phenyl-1, 3-thiazole as a starting material. The synthesised compounds have been screened in vitro for their antimicrobial acti...
متن کاملSynthesis, Characterization, and Chelating Properties of 4-nitrobenzoylsemicarbazone-1- Phenyl-3-methyl-2-pyrazolin-5-one (nbmp-sc)
4-Nitrobenzoylsemicarbazone-1-phenyl-3-methyl-2-pyrazolin-5-one (NBMP-SC) was prepared and its metal chelates of Cu,Ni,Co,Mn,Fe,Fe,Cr,UO2 and OV were prepared. The ligands and its chelates were characterized by elemental analysis, Metal: ligand (M:L) stoichiometry, IR-electronic spectral studies and magnetic properties. The compounds also were screened for their antimicrobial activity.
