An efficient and green approach : one pot, multi component, reusable catalyzed synthesis of pyranopyrazoles and investigation of biological assays

Abstract EN

An ecofriendly itinerary for the synthesis of pyranopyrazole derivatives having thioether link has been established via reusable, green catalyst, green solvent and multicomponent domino approach.

To avoid impurities, usage of toxic solvents, toxic catalyst, simple workup and quantitative yields were strategies of this method.

In addition, all the reported compounds were tested for their antioxidant and antibacterial properties.

Some compounds displayed higher antioxidant activity than the standard drug (6a and 6j), while some other active compounds showed prominent antibacterial activity (6e and 6n).

The results demonstrated that these active compounds may be used to support as a decent stand for further investigation in a way to ascertain innovative antioxidant and antibacterial medicines.
