SYNTHESIS AND BIOLOGICAL INVESTIGATION OF NOVEL SPIROOXINDOLE DERIVATIVES PREPARED BY 1, 3-DIPOLAR CYCLOADDITION

Spirooxindole derivatives constitute an important class of heterocyclic compounds owing to their diverse biological activities and broad therapeutic potential. In the present study, a series of novel spirooxindole derivatives were synthesized through a one-pot three-component 1,3-dipolar cycloaddition reaction involving naphthoquinone, isatin ...
