Nanoparticles‐Catalyzed Synthesis of Oxindoles Derivatives

ABSTRACT Oxindole derivatives constitute an important class of heterocyclic compounds with wide‐ranging relevance in medicinal chemistry as well as organic synthesis. The structural versatility and biological significance of this scaffold have garnered significant attention to develop efficient and sustainable synthetic methodologies. However, traditional routes for synthesis of oxindoles have long dominated this field; recent years have seen a growing impact on nanoparticles catalyzed methodologies due to sustainability, cost‐effectiveness, and recyclability. This review examines diverse nanocatalyzed approaches to synthesize oxindole derivatives. The article provides a comprehensive overview of the topic including synthesis of various catalysts and mechanistic insights. The main purpose of this review is to further exploit wider catalytic applications for the synthesis of target compounds.
