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 کاملComparative study of the alkyl and peroxy radical-scavenging activity of 2-t-butyl-4-methoxyphenol (BHA) and its dimer, and their theoretical parameters.
BACKGROUND 2-t-Butyl-4-methoxyphenol (BHA) has considerable toxicity and undesirable potential tumor-promoting activities. To clarify the free radical mechanism of BHA-induced toxicity, the comparative radical-scavenging activity of BHA and its dimer (bis-BHA, 3,3'-ditert-butyl-5,5'-dimethoxy-1,1'-biphenyl-2,2'-diol) with or without 2-mercapto-1-methylimidazole (MMI) was studied using the induc...
متن کاملSynthesis of alkyl 2-(4-oxoquinazolin-3(4H)-yl) acrylate by nucleophilic additionof alkyl propiolates catalysed by Ph3P
4-Hydroxyquinazoline undergoes neutral conditions with alkyl propiolates in the presence of triphenylphosphine (0.26g), and by α substituation the corresponding 2-(4-oxoquinazolin-3(4H)-yl acrylate was obtained in good yields.
