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 کاملPreparation and NMR, Mass and Mössbauer Studies of Di-and Triorganotin (IV) Derivatives of 3-(2-Furanyl)-2- Propenoic Acid
3-(2-Furanyl)-2-propenoic acid has been used to prepare a new series of organotin complexes of general formula R3SnL (R=Me, Et, n-Bu, Ph and Cy) and R2SnL2 (R=Me and n-Bu). These complexes have been characterized by elemental analyses, IR, 1H-NMR, MASS and Mössbaure spectroscopy.

متن کاملSolvent Effects on Structure and Reaction Mechanism: A Theoretical Study of [2 + 2] Polar Cycloaddition between Ketene and Imine
The effects of aqueous solvent on structures and mechanism of the [2 + 2] cycloaddition between ketene and imine were investigated by using correlated MP2 and MP4 levels of ab initio molecular orbital theory in conjunction with the dielectric continuum Generalized Conductor-like Screening Model (GCOSMO) for solvation. We found that reactions in the gas phase and in aqueous solution have very di...
متن کاملThe three-component reaction of 2-(2-oxopropyl)isoindoline-1,3-dione with alkyl isocyanides and aromatic carboxylic acids under catalyst-free conditions in water
A green and convenient protocol is described for the preparation of 1-(alkylamino)-3-(1,3-dioxoisoindolin-2-yl)-2-methyl-1-oxopropan-2-yl benzoates via one-pot three-component reaction between 2-(2-oxopropyl)isoindoline-1,3-dione, an alkyl isocyanide and an aromatic carboxylic acid in water at room temperature. The methods used to follow the reactions are TLC and NMR, which indicated that there...
