Heterogeneously Catalyzed “One-Pot” Synthesis of Quinoline Derivatives: A Comprehensive Review

Compounds containing quinoline, found in both natural and synthetic sources, represent a significant category of heterocyclic compounds. In this regard, the enhancement of sustainable catalytic materials for the eco-friendly and efficient synthesis of fine chemicals is a highly relevant issue. Quinoline derivatives have been synthesized by some routes that possess specific advantages, i.e., reducing waste production, atom economy, applying safer reagents and solvents, and being environmentally friendly. Several heterogeneous catalysts have recently been developed and successfully used in organic synthesis due to economic and environmental reasons. This review will focus on the recent achievements in the synthesis of quinolines using different reusable heterogeneous catalysts over the last decade.
