Multicomponent synthesis of pyranopyrazole derivatives by using montmorillonite K‐10 as a reusable green acid catalyst under eco‐friendly method in the presence of eco‐friendly solvent leads to novel protocol. Moreover, catalyst could be reused five times for the reaction without noticeable loss of activity. The scope of this path was to develop new synthetic molecules by using green catalysis for further
The paper describes the results of a new four-component synthesis of pyranopyrazole heterocycles by solvent-free one-pot grinding of malononitrile, hydrazine, ethyl acetoacetate, and various aldehydes in the presence of a base. The reaction proceeded smoothly at room temperature with good yields in very short reaction time. The synthesised compounds were evaluated for their in vitro antibacterial activity against three different bacterial and three different fungal strains. The highlight of this work is that the synthesis was activity-driven. The brief SAR correlation found that the tested compounds showed better activity against fungal strains.

the present work synthesis, simulation, and antimicrobial studies of pyranopyrazole derivatives were discussed. Among the reported compounds, 4b has dominant antimicrobial activity that was due to its higher dipolemoment. Also, this compound has the most hydrophilic nature and low E g value. Besides, compound 4e has the next higher dipolemoment, hydrophilic property and efficient biological activity
