In the present study, a series of novel highly functionalized spiropyrrolidine-oxindoles have been synthesized through 1,3-dipolar cycloaddition of an azomethine ylide formed from isatin and various amino acids such as sarcosine, proline and thioproline with the dipolarophile (E)-3-(1,3-diphenyl-1H-pyrazol-4-yl)-2-(1H-indole-3-carbonyl)acrylonitrile under optimized conditions. All the synthesized compounds were evaluated for their antimicrobial activity and shown significant activity.
Keywords: Antimicrobial activity; Molecular docking; Multicomponent reaction; Pyrazole moiety; Spirooxindole.
