a series of n-substituted-2,4-thiazolidinedione derivatives (tzds) were prepared via n-alkylation of 2,4-tzd at position 3 using substituted benzyl halides. synthesized n-substituted-2,4-tzd was then substituted at position 5 with substituted aromatic aldehyde according to knoevenagel condensation method. structures of the compounds were elucidated using various spectral techniques viz. ir, 1hn...

Coumarin derivatives have shown different biological activities, such as antifungal, antibacterial antiinflammatory, and antioxidant besides antibiotic resistance modulating effects, anti-HIV, hepatoprotective, antitumor effect. So, new coumarin (hydrazones an amide) were synthesized through multisteps reactions. All the target compounds characterized by FT-IR spectroscopy, 1HNMR analysis. The ...

The characterization and design of this study new liquid crystals with a V shape compounds containing thiazolidine-2,4-dione 1,3-phenylene as core unite mesophase properties were reported. Preparation chloroacetic acid, water, thiourea to produce [I] in the presence strong hydrochloric acid. 4-hydreoxybenzaldehyde n-alkyl bromide reacted potassium hydroxide create n-alkoxy benzaldehyde., then c...

New N-substituted ?-aminonitrile derivatives from menthol were synthesized by consecutive succinic ester formation, propargylation, 1,3-dipolar Huisgen cycloaddition and Strecker reaction. The structures of the compounds confirmed diverse spectroscopic techniques including 1HNMR, 13C-NMR, ESI-MS IR. novel evaluated for their in vitro antibacterial activities against Staphylococcus aureus as Gra...

In this study, a class of bis-1,2-(4-aryl-2-alkyl-1H- inden-1-yl) ethane was synthesized and characterized by spectroscopic methods such as 1HNMR, 13CNMR, melting point and FTIR. bis-1,2-(4-aryl-2-alkyl-1H- inden-1-yl) ethane was synthesized by the reaction of butyl­lithium, arylindenes and dibromoethane in a facile, one-pot strategy. It’s shown that these methods have a wide scope to afford li...

ethylammonium propionate with high polarity and ionic conductivity was synthesized andcharacterized with 1hnmr and ir. this ionic liquid which is prepared from readily available startingmaterial in high yield shows reasonably high at viscosity and heat stability up to 150 °c. this ionicliquid is able to dissolve most of organic solvents due to the hydrogen interaction between ionicliquid and th...
