Oxidative Difunctionalization

Transition metals are the dominant catalysts for redox-reactions between peroxides and organic substrates. Here, we show that triarylamines can act as organic redox-catalysts, enabling oxidative difunctionalization reactions of alkenes and...

Synthesis And Biological Evaluation

In the present work, novel pyrazole fused dihydrofurans synthesized via a chronological addition of N-chloro succinimide and base piperidine to pyrano[3,2-c]pyrazole carbonitrile derivatives in methanol medium. Oxidative difunctionalization was done with the reagent N-chloro succinimide by the addition of both chlorine and alkoxy groups crosswise the chromene double bond. The addition of base results in the construction of dihydrofuran derivatives by ring contraction. The structures of newly synthesized compounds were characterized on the basis of physical and spectral data. Synthesized compounds were evaluated for antibacterial and anti-inflammatory activities. All the compounds exhibited significant antibacterial activity against all the four strains of bacteria and their MICs ranged between 1.56 and 12.55 μg/mL. In anti-inflammatory screening, among all the tested compounds, compounds 7, 8, 9, 11, 12, 13, 14, 16, 17 and 18 exhibited significant protection against the edema formation at a concentration of 100 mg/kg.
